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 3-((1,3,4-Thiadiazol-2-yl)thio)dihydrofuran-2(3H)-one.
3-((1,3,4-Thiadiazol-2-yl)thio)dihydrofuran-2(3H)-one (CAS 1197776-58-1), molecular formula C6H6N2O2S2 and molecular weight 202.25 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-((1,3,4-Thiadiazol-2-yl)thio)dihydrofuran-2(3H)-one (C6H6N2O2S2) 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 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), 3-((1,3,4-Thiadiazol-2-yl)thio)dihydrofuran-2(3H)-one 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.
