Chemical Structure
Description
N2,N6,N6,5,7-Pentamethyl-3-(phenylsulfonyl)pyrazolo[1,5-a]pyrimidine-2,6-diamine (CAS 1220646-23-0), molecular formula C17H21N5O2S and molecular weight 359.45 g/mol, is a CATO reference standard with documented purity and traceability.
N2,N6,N6,5,7-Pentamethyl-3-(phenylsulfonyl)pyrazolo[1,5-a]pyrimidine-2,6-diamine (C17H21N5O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures N2,N6,N6,5,7-Pentamethyl-3-(phenylsulfonyl)pyrazolo[1,5-a]pyrimidine-2,6-diamine 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.
