Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Iodo-1,2,4-thiadiazole.
5-Iodo-1,2,4-thiadiazole (CAS 1597642-19-7), molecular formula C2HIN2S and molecular weight 212.01 g/mol, is a CATO reference standard with documented purity and traceability.
5-Iodo-1,2,4-thiadiazole (C2HIN2S) contains a nitrile group, sulfur-containing functionality, iodine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), 5-Iodo-1,2,4-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.
