Физические свойства
Pantothenic acid is composed of β-alanine joined to 2,4-dihydroxy-3,3- dimethylbutyric acid via an amide linkage. The molecule has an asymmetric center, and only the R-enantiomer, usually called D-(+)pantothenic acid, is biologically active and occurs naturally. Appearance: pantothenic acid is a yellow, viscous oil. Its calcium and other salts, however, are colorless crystalline substances; calcium pantothenate is the main product of commerce. Solubility: neither form is soluble in organic solvents, but each is soluble in water and ethanol. Stability: aqueous solu tions of pantothenic acid are unstable when heated under acidic or alkaline conditionsИспользование
Labelled Pantothenic AcidПрофиль безопасности
Moderately toxic by subcutaneous and intraperitoneal routes. When heated to decomposition it emits toxic vapors of NOx.Пантотеновая кислота запасные части и сырье
