(Z)-[2-(Benzenesulfonyl)-1-[2-(4-chlorophenyl)-4-methyl-1,3-thiazol-5-yl]ethylidene][(4-fluorophenyl)methoxy]amine (CAS 672950-32-2), molecular formula C25H20ClFN2O3S2 and molecular weight 515.02 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (Z)-[2-(Benzenesulfonyl)-1-[2-(4-chlorophenyl)-4-methyl-1,3-thiazol-5-yl]ethylidene][(4-fluorophenyl)methoxy]amine (C25H20ClFN2O3S2) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 515.02 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.
