2-((4-Phenoxyphenyl)amino)-4H-benzo[d][1,3]oxazin-4-one CAS 282529-86-6

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-Phenoxyphenyl)amino)-4H-benzo[d][1,3]oxazin-4-one.

2-((4-Phenoxyphenyl)amino)-4H-benzo[d][1,3]oxazin-4-one (CAS 282529-86-6) is a high-purity analytical reference standard with the molecular formula C20H14N2O3 and a molecular weight of 330.34 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 2-((4-Phenoxyphenyl)amino)-4H-benzo[d][1,3]oxazin-4-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 330.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
