5-Ethyl-N-(2-isobutyryl-1,2,3,4-tetrahydroisoquinolin-7-yl)thiophene-2-sulfonamide (CAS 955720-99-7), molecular formula C19H24N2O3S2 and molecular weight 392.54 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 5-Ethyl-N-(2-isobutyryl-1,2,3,4-tetrahydroisoquinolin-7-yl)thiophene-2-sulfonamide (C19H24N2O3S2) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 392.54 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).
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.
