In 1866, Choline (CAS NO.62-49-7) was discovered by Andreas Strecker in 1864 and chemically synthesized.
In 1998 choline was classified as an essential nutrient by the Food and Nutrition Board of the Institute of Medicine (U.S.A.).

Reported in EPA TSCA Inventory.

The Choline, with the CAS registry number 62-49-7, is also known as (2-Hydroxyethyl)trimethylammonium. Its EINECS number is 200-535-1. This chemical's molecular formula is C₅H₁₄NO and molecular weight is 104.17. What's more, its systematic name is 2-Hydroxy-N,N,N-trimethylethanaminium. Its classification codes are: (1)Antimetabolites; (2)Central Nervous System Agents; (3)Gastrointestinal Agents; (4)Hypolipidemic Agents; (5)Lipid Regulating Agents; (6)Lipotropic agents; (7)Nootropic agents. This chemical is a basic constituent of lecithin that is found in many plants and animal organs. It is important as a precursor of acetylcholine, as a methyl donor in various metabolic processes, and in lipid metabolism. This substance is a water-soluble essential nutrient. It is usually grouped within the B-complex vitamins. Choline generally refers to the various quaternary ammonium salts.

Physical properties of Choline are: (1)ACD/LogP: -4.141; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): -4.14; (4)ACD/LogD (pH 7.4): -4.14; (5)ACD/BCF (pH 5.5): 1.00; (6)ACD/BCF (pH 7.4): 1.00; (7)ACD/KOC (pH 5.5): 1.00; (8)ACD/KOC (pH 7.4): 1.00; (9)#H bond acceptors: 2; (10)#H bond donors: 1; (11)#Freely Rotating Bonds: 3; (12)Polar Surface Area: 20.23 Å².

Uses of Choline: it can be used to produce (2-{[2-(6-amino-purin-9-yl)-ethoxymethyl]-hydroxy-phosphinoyloxy}-ethyl)-trimethyl-ammonium at the ambient temperature. It will need reagent thionyl chloride and solvent dimethylformamide with the reaction time of 16 hours. The yield is about 38%.
