Description
5-[(2Z)-1-[3-Chloro-5-(trifluoromethyl)pyridin-2-yl]-2-{[(4-chlorophenyl)methoxy]imino}ethyl]-N,N-diethylthiophene-2-sulfonamide (CAS 344278-63-3) is a high-purity analytical reference standard with the molecular formula C23H22Cl2F3N3O3S2 and a molecular weight of 580.47 g/mol.
Structurally, 5-[(2Z)-1-[3-Chloro-5-(trifluoromethyl)pyridin-2-yl]-2-{[(4-chlorophenyl)methoxy]imino}ethyl]-N,N-diethylthiophene-2-sulfonamide (C23H22Cl2F3N3O3S2) 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 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 580.47 g/mol, it falls into the moderately-high-molecular-weight range. 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.
