2-Ethoxy-5-methyl-1,3,4-thiadiazole CAS 1925-77-5 chemical structure

Description

CATO supplies 2-Ethoxy-5-methyl-1,3,4-thiadiazole (CAS 1925-77-5), a certified reference material (molecular formula C5H8N2OS, MW 144.19 g/mol) for analytical method development and quality control.

2-Ethoxy-5-methyl-1,3,4-thiadiazole (C5H8N2OS) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 2-Ethoxy-5-methyl-1,3,4-thiadiazole 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.
