Choline [62-49-7], also known as trimethyl(2-hydroxyethyl)ammonium hydroxide, is a quaternary ammonium compound with the molecular formula C₅H₁₅O₂N. It was first isolated from pig bile in 1849 by Stecker and is subsequently found in brain tissue.
2-Chlorophenol, also known as ortho-chlorophenol, is an aromatic compound with the chemical formula C6H4ClOH. It is a liquid with a strong, unpleasant odor.
Propylene chlorohydrin is a general term that refers to the two isomers of chloropropanol (1-chloro-2-propanol and 2-chloro-l-propanol) with the chemical formula C3H7ClO. It is a colorless liquid with a pleasant odor, and it is soluble in water and organic solvents.
2-Chloroethanol, also known as ethylene chlorohydrin, is an organic chemical compound with the formula HOCH2CH2Cl. It is a colorless liquid with a pleasant odor that was an important intermediate used in the past to produce ethylene oxide, but that is no longer the case.
Dichloromethane, also known as methylene chloride, or DCM, is a colorless, highly volatile liquid with a sweet, chloroform-like odor. Its chemical formula is CH2Cl2, and it is a widely used industrial solvent with a variety of applications. It represents 25% of the total production of chloromethanes (CH3Cl, CH2Cl2, CHCl3, and CCl4).
Trichloroacetaldehyde [75-87-6], also known as chloral or 2,2,2-trichloroethanal, is an organic compound with the formula CCl3CHO. It is a colorless liquid that was first produced in 1832 by Justus von Liebig through the chlorination of ethanol.
Dichloroacetaldehyde [79-02-7], or 2,2-dichloroethanal, is a chlorinated acetaldehyde with the chemical formula Cl2CHCHO. It is a colorless liquid with a pungent, irritating odor that was produced for the first time in 1868 by F. Paterno by distillation of dichlorodiethyl acetal, CHCl2CH(OC2H5)2, with sulfuric acid.
Chloroacetaldehyde [107-20-0], also known as 2-chloroethanal, is an organic compound with the formula CH2ClCHO. It is a colorless liquid that was first produced in pure form by K. Natterer in 1882 by heating chloroacetaldehyde diethyl acetal with anhydrous oxalic acid at 100–150 °C.
Tetrachloromethane, also known as carbon tetrachloride, is an organic compound with the formula CCl4. It is a colorless volatile liquid with a characteristic odor that was used as an industrial solvent with a wide range of applications. However, its potent toxicity and harmful environmental impact have led to a significant decline in its use in recent decades.
Trichloromethane, also known as chloroform [67-66-3], is an organic compound with the chemical formula CHCl3. It is a clear, colorless liquid with a sweet yet pungent odor. Historically, it was used in anesthesia and as a solvent, but due to its toxicity, it has been substituted by safer products.
Chloromethane, also known as methyl chloride, is the simplest chlorinated derivative of methane with the chemical formula CH3Cl. It's a colorless gas with a faint, sweet odor that occurs naturally in trace amounts but is primarily produced industrially.
Carbazole is a heterocyclic aromatic hydrocarbon with the chemical formula C12H9N. It was first isolated from coal tar in 1872 by Graebe and Glaser. Its structure features a dibenzopyrrole, consisting of a five-membered nitrogen-containing ring fused to two benzene rings.
