Aggregated GHS information provided per 6 reports by companies from 2 notifications to the ECHA C&L Inventory. Each notification may be associated with multiple companies.
Chemical: D-Alanine
D-Alanine: Does not have an individual approval but may be used under an appropriate group standard
使用D-Alanine is essential for the biosynthesis of peptidoglycan crosslinking sub-units that are used for bacterial cell walls.
一般的な説明Alanine is a non essential amino acid.
製造方法D-Alanine can be obtained by hydrolysis and refining of proteins such as gelatin, sericin and corn protein, or it can be synthesized by chemical methods.
純化方法Crystallise alanine from H2O or aqueous EtOH, i.e. crystallise it from 25% EtOH in water, or recrystallise it from 62.5% EtOH, wash it with EtOH and dry it to constant weight in vacuo over P2O5. [Gutter & Kegeles J Am Chem Soc 75 3893 1953, Walsh J Biol Chem 264 2394 1989.] 2,2'-Iminodipropionic acid is a likely impurity. [Beilstein 4 IV 2480. 2481.]
