Chemical Structure
Description
CATO supplies (1-Isopropyl-1h-1,2,4-triazol-5-yl)methanesulfonyl chloride (CAS 1487327-17-2), a certified reference material (molecular formula C6H10ClN3O2S, MW 223.68 g/mol) for analytical method development and quality control.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, (1-Isopropyl-1h-1,2,4-triazol-5-yl)methanesulfonyl chloride is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 223.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
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), (1-Isopropyl-1h-1,2,4-triazol-5-yl)methanesulfonyl 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.
