| | Mucochloric acid Usage And Synthesis |
| Chemical Properties | WHITE TO LIGHT BEIGE CRYSTALLINE POWDER | | Uses | Mucochloric Acid is an intermediate product of the herbicide Burex that can cause poisioning and skin damage upon exposure. Mucochloric Acid is also a chlorine disinfection byproduct in drinking water with mutagenic activity. | | Safety Profile | Poison by ingestion.
Moderate skin and severe eye irritant.
Questionable carcinogen with experimental
tumorigenic data. Mutation data reported.
When heated to decomposition it emits
toxic fumes of Cl-. | | Purification Methods | Crystallise the acid twice from water (charcoal). [Beilstein 3 IV 1720.] |
