Glutaraldehyde is an organic compound with the formula (CH2)3(CHO)2. The molecule consists of a five carbon chain doubly terminated with formyl (CHO) groups. It is usually used as a solution in water, and such solutions exists as a collection of hydrates, cyclic derivatives, and condensation products, several of which interconvert. Because the molecule has two aldehyde functional groups, glutaraldehyde (and its hydrates) can crosslink substances with primary amine groups, through condensation. Crosslinking can rigidify and deactivate proteins and other molecules that are critical for normal biological function, such as DNA, and so glutaraldehyde solutions are effective biocides and fixatives. It is sold under the brandnames Cidex and Glutaral. [3] [4] [5] [6] As a disinfectant, it is used to sterilize surgical instruments. [3]

Uses

Biochemistry

Glutaraldehyde is used in biochemistry applications as an amine-reactive homobifunctional crosslinker and fixative. [7] [8] It kills cells quickly by crosslinking their proteins. It is usually employed alone or mixed with formaldehyde [9] as the first of two fixative processes to stabilize specimens such as bacteria, plant material, and human cells. A second fixative procedure uses osmium tetroxide to crosslink and stabilize cell and organelle membrane lipids.

Another application for treatment of proteins with glutaraldehyde is the inactivation of bacterial toxins to generate toxoid vaccines, e.g., the pertussis (whooping cough) toxoid component in the Boostrix Tdap vaccine produced by GlaxoSmithKline. [10]

Material Science

In material science glutaraldehyde application areas range from polymers to metals and biomaterials. Glutaraldehyde is commonly used as fixing agent before characterization of biomaterials for microscopy. Glutaraldehyde is a powerful crosslinking agent for many polymers containing primary amine groups. [11] [12] Glutaraldehdye also can be used for an interlinking agent to improve the adhesion force between two polymeric coatings. [13] Glutaraldehyde is also used to protect against corrosion of undersea pipes. [14]

Medical

Clinical uses

Glutaraldehyde is used as a disinfectant and medication. [3] [4] [15] Usually applied as a solution, it is used to sterilize surgical instruments and other areas. [3]

Dermatological uses

As a medication it is used to treat plantar warts. [4] For this purpose, a 10% w/v solution is used. It dries the skin, facilitating physical removal of the wart. [16]

Glutaraldehyde is also used in the treatment of hyperhidrosis under the control of dermatologists in people who have frequent sweating but do not respond to aluminum chloride. Glutaraldehyde solution is an effective agent to treat palmar and plantar hyperhidrosis as an alternative to tannic acid and formaldehyde. [17]

Other Uses

Aquaria

Glutaraldehyde diluted with water is often marketed as alternative to carbon dioxide gas injection for aquarium plants, but it lacks any characteristics that promote the growth of aquatic plants, and does not raise the CO2 concentration of water it is added to [ citation needed ]. Aquarists also commonly use it in low concentrations as an algicide. [18]

Safety

Side effects include skin irritation. [4] If exposed to large amounts, nausea, headache, and shortness of breath may occur. [3] Protective equipment is recommended when used, especially in high concentrations. [3] Glutaraldehyde is effective against a range of microorganisms including spores. [3] [19] Glutaraldehyde is a dialdehyde. [20] It works by a number of mechanisms. [19]

As a strong sterilant, glutaraldehyde is toxic and a strong irritant. [21] There is no strong evidence of carcinogenic activity, [22] However, some occupations that work with this chemical have an increased risk of some cancers. [22]

Production and reactions

Production

Glutaraldehyde is produced industrially by the catalytic oxidation of cyclopentene by hydrogen peroxide, which can be achieved in the presence of various tungstic acid-based heteropoly acid catalysts. [23] [24] This reaction essentially mimics ozonolysis. Alternatively it can be made by the Diels-Alder reaction of acrolein and vinyl ethers followed by hydrolysis. [25]

Reactions

Like other dialdehydes, (e.g., glyoxal) and simple aldehydes (e.g., formaldehyde), glutaraldehyde hydrates in aqueous solution, forming gem-diols. These diols in turn equilibrate with cyclic hemiacetal. [26] [25] [7] Monomeric glutaraldehyde polymerizes by aldol condensation and Michael reactions yielding alpha, beta-unsaturated poly-glutaraldehyde and related oligomers. This reaction occurs at alkaline pH values. [27]

A number of mechanisms have been invoked to explain the biocidal and fixative properties of glutaraldehyde. [19] Like many other aldehydes, it reacts with primary amines and thiol groups, which are common functional groups in proteins, nucleic acids and polymeric materials. Being bi-functional, glutaraldehyde is a crosslinker, which rigidifies macromolecular structures and shuts down their reactivity. [28]

The aldehyde groups in glutaraldehyde are susceptible to formation of imines by reaction with the amines of lysine and nucleic acids. The derivatives from aldol condensation of pairs of glutaraldehyde also undergo imine formation. [27]

Formaldehyde ( for-MAL-di-hide, fər-) (systematic name methanal) is an organic compound with the chemical formula CH2O and structure H−CHO, more precisely H2C=O. The compound is a pungent, colourless gas that polymerises spontaneously into paraformaldehyde. It is stored as aqueous solutions (formalin), which consists mainly of the hydrate CH2(OH)2. It is the simplest of the aldehydes (R−CHO). As a precursor to many other materials and chemical compounds, in 2006 the global production of formaldehyde was estimated at 12 million tons per year. It is mainly used in the production of industrial resins, e.g., for particle board and coatings. Small amounts also occur naturally.

In organic chemistry, an acetal is a functional group with the connectivity R2C(OR')2. Here, the R groups can be organic fragments or hydrogen, while the R' groups must be organic fragments not hydrogen. The two R' groups can be equivalent to each other or not. Acetals are formed from and convertible to aldehydes or ketones and have the same oxidation state at the central carbon, but have substantially different chemical stability and reactivity as compared to the analogous carbonyl compounds. The central carbon atom has four bonds to it, and is therefore saturated and has tetrahedral geometry.

Sterilization refers to any process that removes, kills, or deactivates all forms of life and other biological agents present in or on a specific surface, object, or fluid. Sterilization can be achieved through various means, including heat, chemicals, irradiation, high pressure, and filtration. Sterilization is distinct from disinfection, sanitization, and pasteurization, in that those methods reduce rather than eliminate all forms of life and biological agents present. After sterilization, an object is referred to as being sterile or aseptic.

<span class="mw-page-title-main">Dicarbonyl</span> Molecule containing two adjacent C=O groups

In organic chemistry, a dicarbonyl is a molecule containing two carbonyl groups. Although this term could refer to any organic compound containing two carbonyl groups, it is used more specifically to describe molecules in which both carbonyls are in close enough proximity that their reactivity is changed, such as 1,2-, 1,3-, and 1,4-dicarbonyls. Their properties often differ from those of monocarbonyls, and so they are usually considered functional groups of their own. These compounds can have symmetrical or unsymmetrical substituents on each carbonyl, and may also be functionally symmetrical or unsymmetrical.

In organic chemistry, the Mannich reaction is a three-component organic reaction that involves the amino alkylation of an acidic proton next to a carbonyl functional group by formaldehyde and a primary or secondary amine or ammonia. The final product is a β-amino-carbonyl compound also known as a Mannich base. Reactions between aldimines and α-methylene carbonyls are also considered Mannich reactions because these imines form between amines and aldehydes. The reaction is named after Carl Mannich.

Thiazolidine is a heterocyclic organic compound with the formula (CH2)3(NH)S. It is a 5-membered saturated ring with a thioether group and an amine group in the 1 and 3 positions.
