L-Cysteine hydrochloride anhydrous Chemical Properties,Uses,Production

Chemical Properties

solid

Uses

As dough conditioner.

Definition

ChEBI: A hydrochloride obtained by combining L-cysteine with one molar equivalent of hydrogen chloride.

Safety Profile

: Moderately toxic by intraperitoneal, intravenous, and possibly other routes. Mutation data reported. When heated to decomposition it emits very toxic fumes of NOx, SOx, and Cl-.

Purification Methods

Likely impurities are cystine and tyrosine. Crystallise the salt from MeOH by adding diethyl ether, or from hot 20% HCl. Dry it under vacuum over P2O5. Hygroscopic. [Beilstein 4 III 1580, 1600.]
