Chemical Structure
Description
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.
CATO supplies 7-(Dimethylamino)-1-hydroxy-3H-phenoxazin-3-one (CAS 13972-90-2), a certified reference material (molecular formula C14H12N2O3, MW 256.26 g/mol) for analytical method development and quality control.
The molecular framework of 7-(Dimethylamino)-1-hydroxy-3H-phenoxazin-3-one (C14H12N2O3) 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 the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 7-(Dimethylamino)-1-hydroxy-3H-phenoxazin-3-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.
