Dapsone is an antibiotic and anti-inflammatory drug used primarily in the treatment of leprosy and dermatitis herpetiformis. It is also used in combination therapies for Pneumocystis pneumonia in immunocompromised patients. It works by inhibiting bacterial synthesis of dihydrofolic acid.
Cleanchem is a trusted provider of premium pharmaceutical reference materials, specializing in Dapsone and its associated compounds. Our catalog includes pharmacopeial and non-pharmacopeial Dapsone impurities, metabolites, nitrosamine derivatives (N-NO compounds), and stable isotope-labeled products. These reference standards play a critical role in pharmaceutical R&D, supporting activities such as product formulation, ANDA and DMF submissions, quality assurance, analytical method development, and stability assessments.
All Dapsone-related substances undergo comprehensive characterization and are delivered with complete Certificates of Analysis and supporting analytical documentation to ensure regulatory adherence. Upon request, we can offer EP/USP traceable standards. Our products are routinely re-evaluated to maintain consistent quality and performance.
