1-Hexanol (IUPAC name hexan-1-ol) is an organic alcohol with a six-carbon chain and a condensed structural formula of CH3(CH2)5OH. This colorless liquid is slightly soluble in water, but miscible with diethyl ether and ethanol. Two additional straight chain isomers of 1-hexanol, 2-hexanol and 3-hexanol, exist, both of which differing by the location of the hydroxyl group. Many isomeric alcohols have the formula C6H13OH. It is used in the perfume industry.
Acenaphthene is a polycyclic aromatic hydrocarbon (PAH) consisting of naphthalene with an ethylene bridge connecting positions 1 and 8. It is a colourless solid. Coal tar consists of about 0.3% of this compound.

2,6-Di-tert-butylphenol is an organic compound with the structural formula 2,6-((CH3)3C)2C6H3OH. This colorless solid alkylated phenol and its derivatives are used industrially as UV stabilizers and antioxidants for hydrocarbon-based products ranging from petrochemicals to plastics. Illustrative of its usefulness, it prevents gumming in aviation fuels.
Aluminium selenide is the inorganic compound with the formula Al2Se3.
Crotonaldehyde is a chemical compound with the formula CH3CH=CHCHO. The compound is usually sold as a mixture of the E- and Z-isomers, which differ with respect to the relative position of the methyl and formyl groups. The E-isomer is more common (data given in Table is for the E-isomer). This lachrymatory liquid is moderately soluble in water and miscible in organic solvents. As an unsaturated aldehyde, crotonaldehyde is a versatile intermediate in organic synthesis. It occurs in a variety of foodstuffs, e.g. soybean oils.
tert-Butyl chloride is the organochloride with the formula (CH3)3CCl. It is a colorless, flammable liquid. It is sparingly soluble in water, with a tendency to undergo hydrolysis to the corresponding tert-butyl alcohol. It is produced industrially as a precursor to other organic compounds.
Phthalonitrile is an organic compound with the formula C6H4(CN)2, which is an off-white crystal solid at room temperature. It is a derivative of benzene, containing two adjacent nitrile groups. The compound has low solubility in water but is soluble in common organic solvents. The compound is used as a precursor to phthalocyanine and other pigments, fluorescent brighteners, and photographic sensitizers.
Cyclododecane is an organic compound with the chemical formula (CH2)12. It is a waxy white solid at room temperature, and is soluble in nonpolar organic solvents.
Laurolactam is an organic compound from the group of macrocyclic lactams. Laurolactam is mainly used as a monomer in engineering plastics, such as nylon-12 and copolyamides.
2,4-Diaminotoluene is an organic compound with the formula C6H3(NH2)2CH3. It is one isomer of six with this formula. It is a white solid although commercial samples are often yellow-tan.
Anisyl alcohol (4-methoxybenzyl alcohol) is an organic compound with the chemical formula CH3OC6H4CH2OH. It is a colorless liquid that is used as a fragrance and flavorant. It occurs naturally but is produced by reduction of anisaldehyde.
1,4-Dichloro-2-nitrobenzene is an organic compound with the formula C6H3Cl2NO2. One of several isomers of dichloronitrobenzene, it is a yellow solid that is insoluble in water. It is produced by nitration of 1,4-dichlorobenzene. It is a precursor to many derivatives of commercial interest. Hydrogenation gives 1,4-dichloroaniline. Nucleophiles displace the chloride adjacent to the nitro group: ammonia gives the aniline derivative, aqueous base gives the phenol derivative, and methoxide gives the anisole derivative. These compounds are respectively 4-chloro-2-nitroaniline, 4-chloro-2-nitrophenol, and 4-chloro-2-nitroanisole.
2,5-Dichloroaniline is an organic compound with the formula C6H3Cl2NH2. One of six isomers of dichloroaniline, it is a colorless solid that is insoluble in water. It is produced by hydrogenation of 1,4-dichloro-2-nitrobenzene. It is a precursor to dyes and pigments, e.g., Pigment Yellow 10.
Cyclohexadecanone is an organic compound with the formula (CH2)15CO. It is a cyclic ketone, which is a minor component of the musk scent of the civet. Several related derivatives are also important in the fragrance industry, especially those with alkene group in the backbone such as civetone, muscone, and 5-cyclohexadecenone (velvione). It is synthesized from cyclododecanone.
