1,3-Butadiene is the organic compound with the formula CH2=CH-CH=CH2. It is a colorless gas that is easily condensed to a liquid. It is important industrially as a precursor to synthetic rubber. The molecule can be viewed as the union of two vinyl groups. It is the simplest conjugated diene.
A diol is a chemical compound containing two hydroxyl groups. An aliphatic diol is also called a glycol. This pairing of functional groups is pervasive, and many subcategories have been identified.
The 1,3-dipolar cycloaddition is a chemical reaction between a 1,3-dipole and a dipolarophile to form a five-membered ring. The earliest 1,3-dipolar cycloadditions were described in the late 19th century to the early 20th century, following the discovery of 1,3-dipoles. Mechanistic investigation and synthetic application were established in the 1960s, primarily through the work of Rolf Huisgen. Hence, the reaction is sometimes referred to as the Huisgen cycloaddition. 1,3-dipolar cycloaddition is an important route to the regio- and stereoselective synthesis of five-membered heterocycles and their ring-opened acyclic derivatives. The dipolarophile is typically an alkene or alkyne, but can be other pi systems. When the dipolarophile is an alkyne, aromatic rings are generally produced.
Substances, mixtures, and exposure circumstances in this list have been classified as group 1 by the International Agency for Research on Cancer (IARC): The agent (mixture) is carcinogenic to humans. The exposure circumstance entails exposures that are carcinogenic to humans. This category is used when there is sufficient evidence of carcinogenicity in humans. Exceptionally, an agent (mixture) may be placed in this category when evidence of carcinogenicity in humans is less than sufficient. Still, there is sufficient evidence of carcinogenicity in experimental animals and strong evidence in exposed humans that the agent (mixture) acts through a relevant mechanism of carcinogenicity.
Dioxolane is a heterocyclic acetal with the chemical formula (CH2)2O2CH2. It is related to tetrahydrofuran (THF) by replacement of the methylene group (CH2) at 2nd position of THF with an oxygen atom. The corresponding saturated 6-membered C4O2 rings are called dioxanes. The isomeric 1,2-dioxolane (wherein the two oxygen centers are adjacent) is a peroxide. 1,3-dioxolane is used as a solvent and as a comonomer in polyacetals.
Dichloropropane can refer to any of several chemical compounds:
1,3-Beta-glucan synthase is a glucosyltransferase enzyme involved in the generation of beta-glucan in fungi. It serves as a pharmacological target for antifungal drugs such as caspofungin, anidulafungin, and micafungin, deemed 1,3-Beta-glucan synthase inhibitors. Under the CAZy classification system, fungi and plant members fall in the glycosyltransferase 48 family (GT48). Some members of the glycosyltransferase 2 family, such as the curdlan synthase CrdS, also has a similar activity.
Pyrazolidine is a heterocyclic compound. It is a liquid that is stable in air, but it is hygroscopic.
Galactoside 3(4)-L-fucosyltransferase is an enzyme that in humans is encoded by the FUT3 gene.
Alpha-(1,3)-fucosyltransferase is an enzyme that in humans is encoded by the FUT6 gene.
3-MCPD (3-monochloropropane-1,2-diol or 3-chloropropane-1,2-diol) is an organic chemical compound with the formula HOCH2CH(OH)CH2Cl. It is a colorless liquid. It is a versatile multifunctional building block. The compound has attracted attention as the most common member of chemical food contaminants known as chloropropanols. It is suspected to be carcinogenic in humans.
Phenpromethamine, also known as N,β-dimethylphenethylamine, is a sympathomimetic nasal decongestant of the phenethylamine group. It was previously marketed as a nasal inhaler from 1943 through 1960 but is no longer available. The medication is a stimulant and is banned by the World Anti-Doping Agency. It has been detected in dietary supplements starting in the 2010s.
Octodrine is a stimulant drug whose pharmacology was studied in a dozen animal studies from the 1940s through the 1970s. These studies found that octodrine can increase blood pressure and cardiac output in animals. The drug was previously approved for use by the FDA as an inhalant and in Germany as an oral agent as part of a multicomponent medication, but is no longer available.
1,3-Bis(diphenylphosphino)propane (dppp) is an organophosphorus compound with the formula Ph2P(CH2)3PPh2. The compound is a white solid that is soluble in organic solvents. It is slightly air-sensitive, degrading in air to the phosphine oxide. It is classified as a diphosphine ligand in coordination chemistry and homogeneous catalysis.
1,3-Indandione (sometimes simply indanedione) is an organic compound with the molecular formula C6H4(CO)2CH2. It is a β-diketone with indane as its structural nucleus. It is a colorless or white solid, but old samples can appear yellowish or even green. It is a popular chemical scaffold (building block of various useful chemical compounds).
The molecular formula C3H6Cl2 (molar mass: 112.98 g/mol, exact mass: 111.9847 u) may refer to:
1,2,3-Trichloropropane (TCP) is an organic compound with the formula CHCl(CH2Cl)2. It is a colorless liquid that is used as a solvent and in other specialty applications.
1,2-Diaminopropane (propane-1,2-diamine) is organic compound with the formula CH3CH(NH2)CH2NH2. A colorless liquid, it is the simplest chiral diamine. It is used as a bidentate ligand in coordination chemistry.
The chemical abbreviation 1,3-DCP may stand for:
