3-(4-Methoxyphenyl)-2,3,4,5-tetrahydro-1,4-benzoxazepin-5-one CAS 866050-77-3

Description

3-(4-Methoxyphenyl)-2,3,4,5-tetrahydro-1,4-benzoxazepin-5-one (CAS 866050-77-3), molecular formula C16H15NO3 and molecular weight 269.30 g/mol, is a CATO reference standard with documented purity and traceability.

3-(4-Methoxyphenyl)-2,3,4,5-tetrahydro-1,4-benzoxazepin-5-one (C16H15NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

CATO manufactures 3-(4-Methoxyphenyl)-2,3,4,5-tetrahydro-1,4-benzoxazepin-5-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.
