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-[(thien-2-ylmethyl)thio]-1,3,4-thiadiazole-2-thiol.
CATO supplies 5-[(thien-2-ylmethyl)thio]-1,3,4-thiadiazole-2-thiol (CAS 852956-31-1), a certified reference material (molecular formula C7H6N2S4, MW 246.40 g/mol) for analytical method development and quality control.
Owing to a nitrile group, sulfur-containing functionality, an aromatic ring system, 5-[(thien-2-ylmethyl)thio]-1,3,4-thiadiazole-2-thiol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 246.40 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
