Ethyl 3-methyl-1,2,4-thiadiazole-5-carboxylate CAS 76162-56-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 3-methyl-1,2,4-thiadiazole-5-carboxylate.

Ethyl 3-methyl-1,2,4-thiadiazole-5-carboxylate (CAS 76162-56-6), molecular formula C6H8N2O2S and molecular weight 172.20 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Ethyl 3-methyl-1,2,4-thiadiazole-5-carboxylate (C6H8N2O2S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), Ethyl 3-methyl-1,2,4-thiadiazole-5-carboxylate 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.
