Description
CATO manufactures 7-Bromopyrazolo[1,5-a]pyrimidine-3-carboxylic acid 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.
7-Bromopyrazolo[1,5-a]pyrimidine-3-carboxylic acid (CAS 1363381-50-3), molecular formula C7H4BrN3O2 and molecular weight 242.03 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 7-Bromopyrazolo[1,5-a]pyrimidine-3-carboxylic acid (C7H4BrN3O2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
