Chemical Structure

Thiazol-2-ylboronic acid CAS 389630-95-9 chemical structure

Description

Thiazol-2-ylboronic acid (CAS 389630-95-9), molecular formula C3H4BNO2S and molecular weight 128.95 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C3H4BNO2S, Thiazol-2-ylboronic acid contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 128.95 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), Thiazol-2-ylboronic acid 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.
