CYSTEIC ACID Usage And Synthesis

Uses

3-Sulfoalanine,

Definition

ChEBI: An amino sulfonic acid that is the sulfonic acid analogue of cysteine.

Purification Methods

Likely impurities are cystine and oxides of cysteine. Crystallise the acid from water by adding 2 volumes of EtOH. It crystallises from H2O as the monohydrate. When recrystallised from aqueous MeOH it has m 264-266o, and the anhydrous acid has m ~260o(dec).
