Description
CATO manufactures Ethyl (4-(chlorocarbonyl)-1,2,3-thiadiazol-5-yl)carbamate 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.
Ethyl (4-(chlorocarbonyl)-1,2,3-thiadiazol-5-yl)carbamate (CAS 68176-63-6) is a high-purity analytical reference standard with the molecular formula C6H6ClN3O3S and a molecular weight of 235.65 g/mol.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, Ethyl (4-(chlorocarbonyl)-1,2,3-thiadiazol-5-yl)carbamate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 235.65 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.
