6-Mercaptopurine Monohydrate (Azathioprine EP Impurity B Monohydrate)(CAS: 6112-76-1)

6-Mercaptopurine Monohydrate (CAS: 6112-76-1) is a chemical compound with the formula C5H4N4O2S·H2O. It is a white crystalline solid, soluble in water, and commonly used as an impurity in pharmaceuticals like Azathioprine. Its structure features a sulfur atom at the 6th position of a purine ring, making it relevant in drug synthesis and metabolic studies.

6-Mercaptopurine Monohydrate (CAS: 6112-76-1) is primarily used as an EP Impurity B in Azathioprine production. It also serves in research for analyzing drug metabolism, as a reference standard in pharmaceutical quality control, and in studies related to nucleoside analogs. Its applications are limited to non-therapeutic contexts due to its role as a byproduct in synthesis processes.

6-Mercaptopurine Monohydrate (CAS: 6112-76-1) is not intended for therapeutic use and may pose toxicity risks if mishandled. Safety precautions include wearing gloves, avoiding inhalation, and following proper waste disposal protocols. It adheres to regulatory standards for chemical handling, but its use in research should comply with safety data sheets (SDS) and OSHA guidelines to ensure minimal exposure.

6-Mercaptopurine Monohydrate (CAS: 6112-76-1) should be stored in a cool, dry place, away from light, at 2-8°C. Maintain low humidity levels and use airtight containers to preserve stability. Store in a desiccator to prevent moisture absorption and ensure compatibility with other chemicals to avoid degradation.
