| 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.] |
