Chemical Structure
Description
The occurrence of Etridiazole is closely related to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Etridiazole (CAS 2593-15-9), molecular formula C5H5Cl3N2OS and molecular weight 247.53 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, Etridiazole is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 247.53 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Etridiazole 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.
