(3-Chloropyridin-4-yl)boronic acid hydrochloride CAS 2377605-75-7

Description

Compared with other compounds in its class, the molecular weight of 193.82 g/mol gives (3-Chloropyridin-4-yl)boronic acid hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(3-Chloropyridin-4-yl)boronic acid hydrochloride (CAS 2377605-75-7) is a high-purity analytical reference standard with the molecular formula C5H5BClNO2HCl and a molecular weight of 193.82 g/mol.

The molecular framework of (3-Chloropyridin-4-yl)boronic acid hydrochloride (C5H5BClNO2HCl) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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.
