Chemical Structure
Description
As a certified reference material (CRM), 2-Methylthiazole-5-sulfonyl chloride 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.
CATO supplies 2-Methylthiazole-5-sulfonyl chloride (CAS 1314977-63-3), a certified reference material (molecular formula C4H4ClNO2S2, MW 197.66 g/mol) for analytical method development and quality control.
Based on its molecular formula C4H4ClNO2S2, 2-Methylthiazole-5-sulfonyl chloride contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 197.66 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
