Description

CATO manufactures 2-(o-Tolyl)-4H-benzo[d][1,3]oxazin-4-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.

2-(o-Tolyl)-4H-benzo[d][1,3]oxazin-4-one (CAS 18595-87-4), molecular formula C15H11NO2 and molecular weight 237.25 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-(o-Tolyl)-4H-benzo[d][1,3]oxazin-4-one (C15H11NO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
