 |  | Cystamine dihydrochloride Usage And Synthesis |  
 | Chemical Properties | white powder |  | Uses | sulfhydryl modifying reagent and heparin antagonist |  | Uses | hepatoprotectant, t-glutaminase inhibitor, heat shock protein promoter, caspase inhibitor |  | Uses | Cystamine dihydrochloride acts as an anti-infective agent, which is used in the treatment of urinary tract infections. It is also used as a radiation-protective agent that interferes with sulfhydryl enzymes. Further, it serves as a heparin antagonist and sulfhydryl modifying reagent. In addition to this, it is used as an inhibitor of TGase. |  | Safety Profile | A poison by 
subcutaneous and intraperitoneal routes. 
Experimental reproductive effects. When 
heated to decomposition it emits very toxic 
fumes of HCl, SOx, and NOx. See also 
SULFIDES. |  | storage | room temperature (desiccate) |  | Purification Methods | Recrystallise the salt by dissolving in EtOH containing a few drops of dry EtOH/HCl, filtering and adding dry Et2O. The solid is dried in a vacuum and stored in a dry and dark atmosphere. It has been recrystallised from EtOH (solubility: 1g in 60mL of boiling EtOH) or MeOH (plates). The free base has b 90-Purification of Biochemicals — Amino Acids and Peptides 100o/0.001mm, 106-108o/5mm and 135-136o/760mm, d 4 1.1559, n D 1.5720.
