5-Chloro-3-{[(4-chlorophenyl)methyl]sulfanyl}-1,2,4-thiadiazole CAS 1454-42-8

Description

The occurrence of 5-Chloro-3-{[(4-chlorophenyl)methyl]sulfanyl}-1,2,4-thiadiazole is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-Chloro-3-{[(4-chlorophenyl)methyl]sulfanyl}-1,2,4-thiadiazole (CAS 1454-42-8), molecular formula C9H6Cl2N2S2 and molecular weight 277.19 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C9H6Cl2N2S2, 5-Chloro-3-{[(4-chlorophenyl)methyl]sulfanyl}-1,2,4-thiadiazole contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 277.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
