| Cysteamine Hydrochloride | | CAS No | 156-57-0 | | Structural formula | HSCH2CH2NH2·HCl | | Properties | white crystalline powder, the specific gravity is 1.3-1.4, melting point is 62-70°CIt is not inflammable and explosive chemicals, it is one kind of unstable matter in the light, it is easy to be oxidized | | Uses | It can be used in the making of cosmetics, feedstuff additive, anti-ulcerative drug, it also can be applied in the making of biochemical reagent and complex agent of heavy meatl ions. It can react with enzyme of human body and stabilize its performace when radiation is existing , therefore, it can be used in the curing of radiation syndrome and the poison of tetraethyl lead. It can be made into tablets or injections. | | Storage and packing | It should be stored in dry, cool and airiness place, avoid insolation and moisture, keep it far away from metal ions. 25kg(99.0%) in double-layer PE bag lined carton, the bag is filled with nitrogen for protection. 75% soulition: 200kg in plastic drum and the drum is filled with nitrogen for protection. | | Production method | This products is made by one kind of unique method developed by our company. As one kind of environmental friendly method, the iron assay of finished product is lowered to 3ppm or even less, therefore this products can meet the demands of those customers who have higher requirement to product quality. | | Quality index | Form 1 | Item | Value | | Solid powder | 75% solution | | Appearance | white crystalline powder | colorless clear liquid | | identification | positive reaction | positive reaction | | Purity | Melting point | 65.0-70.0°C | N/A | | PH | 3.3-5.0 | 4.0-5.0 | | Loss on dry | is not more than 0.5% | N/A | | Heavy meatl | is not more than 0.002% | is not more than 0.002% | | Ferric salt | is not more than 3ppm | is not more than 3ppm | | Sulfate | is not more than 0.01% | is not more than 0.01% | | Residue on ignition | is not more than 0.1% | N/A | | Assay | the assay of C2H7NS•HClshould not be less than 99.0% | the assay of C2H7NS•HClshould not be less than 75.0% |
