n-(3-Chlorophenyl)-2-((5-imino-4,5-dihydro-1,3,4-thiadiazol-2-yl)thio)acetamide CAS 502998-40-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including n-(3-Chlorophenyl)-2-((5-imino-4,5-dihydro-1,3,4-thiadiazol-2-yl)thio)acetamide.

n-(3-Chlorophenyl)-2-((5-imino-4,5-dihydro-1,3,4-thiadiazol-2-yl)thio)acetamide (CAS 502998-40-5), molecular formula C10H9ClN4OS2 and molecular weight 300.79 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, n-(3-Chlorophenyl)-2-((5-imino-4,5-dihydro-1,3,4-thiadiazol-2-yl)thio)acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 300.79 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
