Chemical Structure
Description
The molecular framework of N-(2-(Benzo[d]oxazol-2-yl)phenyl)-4-chlorobenzamide (C20H13ClN2O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO supplies N-(2-(Benzo[d]oxazol-2-yl)phenyl)-4-chlorobenzamide (CAS 477498-93-4), a certified reference material (molecular formula C20H13ClN2O2, MW 348.78 g/mol) for analytical method development and quality control.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
