Description
CATO manufactures 7-Chloro-2,3-dihydro-1H-pyrido[2,3-b][1,4]oxazine 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.
CATO supplies 7-Chloro-2,3-dihydro-1H-pyrido[2,3-b][1,4]oxazine (CAS 1260667-70-6), a certified reference material (molecular formula C7H7ClN2O, MW 170.60 g/mol) for analytical method development and quality control.
The molecular framework of 7-Chloro-2,3-dihydro-1H-pyrido[2,3-b][1,4]oxazine (C7H7ClN2O) is characterized by an amide group, a hydroxyl group, an ether linkage, chlorine 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.
