L-Cysteine hydrochloride anhydrous Usage And Synthesis
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 r, or from hot 20% HCl. Dry it under vacuum over P2O5. Hygroscopic. [Beilstein 4 III 1580, 1600.]
