2-(4-(2-Chlorobenzoyl)-3,4-dihydro-2H-benzo[b][1,4]oxazin-3-yl)acetic acid CAS 439096-40-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(4-(2-Chlorobenzoyl)-3,4-dihydro-2H-benzo[b][1,4]oxazin-3-yl)acetic acid.

2-(4-(2-Chlorobenzoyl)-3,4-dihydro-2H-benzo[b][1,4]oxazin-3-yl)acetic acid (CAS 439096-40-9) is a high-purity analytical reference standard with the molecular formula C17H14ClNO4 and a molecular weight of 331.75 g/mol.

The molecular framework of 2-(4-(2-Chlorobenzoyl)-3,4-dihydro-2H-benzo[b][1,4]oxazin-3-yl)acetic acid (C17H14ClNO4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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 2-(4-(2-Chlorobenzoyl)-3,4-dihydro-2H-benzo[b][1,4]oxazin-3-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.
