2-((6-Chloro-2-(4-methoxyphenyl)-1H-benzo[d]imidazol-1-yl)oxy)acetic acid CAS 338978-98-6 chemical structure

Description

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.

2-((6-Chloro-2-(4-methoxyphenyl)-1H-benzo[d]imidazol-1-yl)oxy)acetic acid (CAS 338978-98-6) is a high-purity analytical reference standard with the molecular formula C16H13ClN2O4 and a molecular weight of 332.74 g/mol.

2-((6-Chloro-2-(4-methoxyphenyl)-1H-benzo[d]imidazol-1-yl)oxy)acetic acid (C16H13ClN2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
