Chemical Structure
Description
The occurrence of 5-((4-Chlorophenyl)sulfinyl)-N-ethyl-1,2,3-thiadiazole-4-carboxamide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-((4-Chlorophenyl)sulfinyl)-N-ethyl-1,2,3-thiadiazole-4-carboxamide (CAS 306977-05-9) is a high-purity analytical reference standard with the molecular formula C11H10ClN3O2S2 and a molecular weight of 315.80 g/mol.
5-((4-Chlorophenyl)sulfinyl)-N-ethyl-1,2,3-thiadiazole-4-carboxamide (C11H10ClN3O2S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 5-((4-Chlorophenyl)sulfinyl)-N-ethyl-1,2,3-thiadiazole-4-carboxamide 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.
