Chemical Structure

(1-(tert-Butyl)-1H-pyrazol-5-yl)boronic acid CAS 1162643-26-6 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (1-(tert-Butyl)-1H-pyrazol-5-yl)boronic acid.

(1-(tert-Butyl)-1H-pyrazol-5-yl)boronic acid (CAS 1162643-26-6) is a high-purity analytical reference standard with the molecular formula C7H13BN2O2 and a molecular weight of 168.00 g/mol.

The molecular framework of (1-(tert-Butyl)-1H-pyrazol-5-yl)boronic acid (C7H13BN2O2) 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.

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.
