Guanine is one of the four nucleobases found in DNA and RNA, along with adenine, cytosine, and thymine. It pairs with cytosine to form base pairs in the DNA double helix. It plays a critical role in cellular processes such as replication, transcription, and translation.
Cleanchem is a trusted provider of premium pharmaceutical reference materials, specializing in Guanine and its associated compounds. Our catalog includes pharmacopeial and non-pharmacopeial Guanine 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 Guanine-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.
