Chemical Structure

2-[(E)-2-(3-Chlorophenyl)ethenyl]-1,3-benzoxazole CAS 338415-67-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-[(E)-2-(3-Chlorophenyl)ethenyl]-1,3-benzoxazole.

2-[(E)-2-(3-Chlorophenyl)ethenyl]-1,3-benzoxazole (CAS 338415-67-1) is a high-purity analytical reference standard with the molecular formula C15H10ClNO and a molecular weight of 255.70 g/mol.

The molecular framework of 2-[(E)-2-(3-Chlorophenyl)ethenyl]-1,3-benzoxazole (C15H10ClNO) is characterized by a nitrogen-containing heterocyclic scaffold, 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.

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.
