(5-Chloro-6-(2-methyl-1H-imidazol-1-yl)pyridin-3-yl)boronic acid CAS 2225178-83-4 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.

CATO supplies (5-Chloro-6-(2-methyl-1H-imidazol-1-yl)pyridin-3-yl)boronic acid (CAS 2225178-83-4), a certified reference material (molecular formula C9H9BClN3O2, MW 237.45 g/mol) for analytical method development and quality control.

Structurally, (5-Chloro-6-(2-methyl-1H-imidazol-1-yl)pyridin-3-yl)boronic acid (C9H9BClN3O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.5, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 237.45 g/mol, it falls into the medium-molecular-weight range. 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.
