Compared with other compounds in its class, the molecular weight of 142.97 g/mol gives 2-Methyl-5-thiazolyl-boronic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-Methyl-5-thiazolyl-boronic Acid (CAS 1190875-47-8), a certified reference material (molecular formula C4H6BNO2S, MW 142.97 g/mol) for analytical method development and quality control.
The molecular framework of 2-Methyl-5-thiazolyl-boronic Acid (C4H6BNO2S) is characterized by an amide group, a sulfone group, a carboxylic acid 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.
CATO manufactures 2-Methyl-5-thiazolyl-boronic Acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
