Chemical Structure

(7-methyl-1H-indazol-5-yl)boronic acid CAS 1245816-07-2 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 (7-methyl-1H-indazol-5-yl)boronic acid (CAS 1245816-07-2), a certified reference material (molecular formula C8H17BN2O2, MW 184.04 g/mol) for analytical method development and quality control.

The molecular framework of (7-methyl-1H-indazol-5-yl)boronic acid (C8H17BN2O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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.

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.
