4-Phenyl-1H-2,3-benzoxazin-1-one CAS 19298-29-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Phenyl-1H-2,3-benzoxazin-1-one.

4-Phenyl-1H-2,3-benzoxazin-1-one (CAS 19298-29-4), molecular formula C14H9NO2 and molecular weight 223.23 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4-Phenyl-1H-2,3-benzoxazin-1-one (C14H9NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 223.23 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 4-Phenyl-1H-2,3-benzoxazin-1-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.
