Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

2-(3-Oxo-3,4-dihydro-2H-benzo[b][1,4]oxazin-7-yl)acetic acid (CAS 1368148-71-3), molecular formula C10H9NO4 and molecular weight 207.18 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-(3-Oxo-3,4-dihydro-2H-benzo[b][1,4]oxazin-7-yl)acetic acid (C10H9NO4) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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).

CATO manufactures 2-(3-Oxo-3,4-dihydro-2H-benzo[b][1,4]oxazin-7-yl)acetic 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.
