Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

Ethyl 2-(2-chloroacetamido)-5-(cyanosulfanyl)-4-phenylthiophene-3-carboxylate (CAS 726151-90-2) is a high-purity analytical reference standard with the molecular formula C16H13ClN2O3S2 and a molecular weight of 380.87 g/mol.

Ethyl 2-(2-chloroacetamido)-5-(cyanosulfanyl)-4-phenylthiophene-3-carboxylate (C16H13ClN2O3S2) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
