Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-bromo-1H-pyrido[2,3-b]pyrazin-2-one.
7-bromo-1H-pyrido[2,3-b]pyrazin-2-one (CAS 959616-05-8), molecular formula C7H4BrN3O and molecular weight 226.03 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 7-bromo-1H-pyrido[2,3-b]pyrazin-2-one (C7H4BrN3O) is characterized by an amide 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.
CATO manufactures 7-bromo-1H-pyrido[2,3-b]pyrazin-2-one 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.
