Chemical Structure

[2-(1-naphthylmethyl)-1H-benzimidazol-1-yl]acetic acid CAS 919939-22-3 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-(1-naphthylmethyl)-1H-benzimidazol-1-yl]acetic acid.

CATO supplies [2-(1-naphthylmethyl)-1H-benzimidazol-1-yl]acetic acid (CAS 919939-22-3), a certified reference material (molecular formula C20H16N2O2, MW 316.35 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, [2-(1-naphthylmethyl)-1H-benzimidazol-1-yl]acetic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 316.35 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.
