Chemical Structure

3-Nitro-N-(2-phenylbenzo[d]oxazol-5-yl)benzamide CAS 331447-57-5 chemical structure

Description

CATO supplies 3-Nitro-N-(2-phenylbenzo[d]oxazol-5-yl)benzamide (CAS 331447-57-5), a certified reference material (molecular formula C20H13N3O4, MW 359.33 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 3-Nitro-N-(2-phenylbenzo[d]oxazol-5-yl)benzamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 359.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

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.
