Choline hydroxide is a strong organic base that is a component of lecithin and also present in sphingomyelin. It is a source of variable methyl groups in the body that act on the synthesis of methyl groups, as well as a precursor of acetylcholine. Choline hydroxide is a quaternary amine base, a colorless crystal with strong hygroscopicity; Easily soluble in water and ethanol, insoluble in non polar solvents such as chloroform and ether.
Choline Hydroxide (CAS 123-41-1) is a quaternary ammonium compound widely used in chemical synthesis, pharmaceuticals, and the production of surfactants. It usually appears as a choline hydroxide solution in water, offering excellent solubility and strong alkalinity. This compound is a key intermediate in various organic reactions and plays an important role in biochemical processes.
Our choline hydroxide solutions are available in various concentrations and are of high purity and stability.
