Description

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.

Ethyl 4-(cyclohexylsulfanyl)-6-oxo-1-phenyl-1,6-dihydropyridazine-3-carboxylate (CAS 339031-39-9), molecular formula C19H22N2O3S and molecular weight 358.45 g/mol, is a CATO reference standard with documented purity and traceability.

Ethyl 4-(cyclohexylsulfanyl)-6-oxo-1-phenyl-1,6-dihydropyridazine-3-carboxylate (C19H22N2O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

As a certified reference material (CRM), Ethyl 4-(cyclohexylsulfanyl)-6-oxo-1-phenyl-1,6-dihydropyridazine-3-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
