CATO supplies Ethyl 3-(2-chlorophenyl)-4-(methylsulfanyl)-2-sulfanylidene-2,3-dihydro-1,3-thiazole-5-carboxylate (CAS 478261-53-9), a certified reference material (molecular formula C13H12ClNO2S3, MW 345.89 g/mol) for analytical method development and quality control.
Structurally, Ethyl 3-(2-chlorophenyl)-4-(methylsulfanyl)-2-sulfanylidene-2,3-dihydro-1,3-thiazole-5-carboxylate (C13H12ClNO2S3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 345.89 g/mol, it falls into the moderately-high-molecular-weight range. 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.
