Chemical Structure
Description
4-Aminomethylbenzeneboronic acid hydrochloride (4-Aminomethylphenyl)boronic acid hydrochloride 4-(Aminomethyl)benzeneboronic acid hydrochloride 4-(Aminomethyl)phenylboronic acid hydrochloride 75705-21-4 (CAS 75705-21-4), molecular formula C7H10BNO2HCl and molecular weight 187.43 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Aminomethylbenzeneboronic acid hydrochloride (4-Aminomethylphenyl)boronic acid hydrochloride 4-(Aminomethyl)benzeneboronic acid hydrochloride 4-(Aminomethyl)phenylboronic acid hydrochloride 75705-21-4 (C7H10BNO2HCl) 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.
