Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Potassium 4-(4-chlorophenyl)-5-thioxo-4,5-dihydro-1,3,4-thiadiazole-2-thiolate (CAS 1049756-11-7) is a high-purity analytical reference standard with the molecular formula C8H4ClN2S3K and a molecular weight of 298.86 g/mol.
Owing to a salt form, a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution, Potassium 4-(4-chlorophenyl)-5-thioxo-4,5-dihydro-1,3,4-thiadiazole-2-thiolate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 298.86 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.
CATO manufactures Potassium 4-(4-chlorophenyl)-5-thioxo-4,5-dihydro-1,3,4-thiadiazole-2-thiolate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
