Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 133.17 g/mol gives Thiazole-5-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Thiazole-5-carboxylic acid (CAS 14527-41-4), a certified reference material (molecular formula C4H7NO2S, MW 133.17 g/mol) for analytical method development and quality control.
Based on its molecular formula C4H7NO2S, Thiazole-5-carboxylic 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 133.17 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), Thiazole-5-carboxylic 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.
