Chemical Structure
Description
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 supplies imidazo[2,1-b][1,3]thiazole-3-carboxylic acid (CAS 479028-73-4), a certified reference material (molecular formula C6H4N2O2S, MW 168.17 g/mol) for analytical method development and quality control.
Based on its molecular formula C6H4N2O2S, imidazo[2,1-b][1,3]thiazole-3-carboxylic acid contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 168.17 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), imidazo[2,1-b][1,3]thiazole-3-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.
