Ethyl 5-chloro-1,2,4-thiadiazole-3-carboxylate CAS 1346147-95-2

Description

Compared with other compounds in its class, the molecular weight of 192.62 g/mol gives Ethyl 5-chloro-1,2,4-thiadiazole-3-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ethyl 5-chloro-1,2,4-thiadiazole-3-carboxylate (CAS 1346147-95-2), molecular formula C5H5ClN2O2S and molecular weight 192.62 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, Ethyl 5-chloro-1,2,4-thiadiazole-3-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 192.62 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.
