Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
6304-21-8 8-methoxy-9-pentofuranosyl-3,9-dihydro-6h-purin-6-one AR-1H4691 (CAS 6304-21-8), molecular formula C9H11NO and molecular weight 149.19 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 6304-21-8 8-methoxy-9-pentofuranosyl-3,9-dihydro-6h-purin-6-one AR-1H4691 (C9H11NO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 149.19 g/mol, it falls into the low-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 6304-21-8 8-methoxy-9-pentofuranosyl-3,9-dihydro-6h-purin-6-one AR-1H4691 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
