Description

The occurrence of (3,5-Dimethyl-1H-pyrazol-4-yl)boronic acid hydrochloride is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (3,5-Dimethyl-1H-pyrazol-4-yl)boronic acid hydrochloride (CAS 1162262-39-6), a certified reference material (molecular formula C5H9BN2O2HCl, MW 176.41 g/mol) for analytical method development and quality control.

Structurally, (3,5-Dimethyl-1H-pyrazol-4-yl)boronic acid hydrochloride (C5H9BN2O2HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.5, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 176.41 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

As a certified reference material (CRM), (3,5-Dimethyl-1H-pyrazol-4-yl)boronic acid hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
