Chemical Structure

3-Hydroxy-2,3-dimethylbutan-2-yl hydrogen (4-(3-chlorophenyl)thiazol-5-yl)boronate CAS 2223039-42-5 chemical structure

Description

The occurrence of 3-Hydroxy-2,3-dimethylbutan-2-yl hydrogen (4-(3-chlorophenyl)thiazol-5-yl)boronate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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-Hydroxy-2,3-dimethylbutan-2-yl hydrogen (4-(3-chlorophenyl)thiazol-5-yl)boronate (CAS 2223039-42-5), a certified reference material (molecular formula C15H19BClNO3S, MW 339.65 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 3-Hydroxy-2,3-dimethylbutan-2-yl hydrogen (4-(3-chlorophenyl)thiazol-5-yl)boronate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 339.65 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
