Chemical Structure
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.
(E)-N'-(Cyclohexyl(phenyl)methylene)-2-(trifluoromethyl)benzenesulfonohydrazide (CAS 2553409-20-2), molecular formula C20H21F3N2O2S and molecular weight 410.45 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (E)-N'-(Cyclohexyl(phenyl)methylene)-2-(trifluoromethyl)benzenesulfonohydrazide (C20H21F3N2O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 410.45 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
