(1r,1's,4R,4'R)-4-(3-fluoro-4-(trifluoromethoxy)phenyl)-4'-propyl-1,1'-bi(cyclohexane) CAS 137810-19-6

Description

The occurrence of (1r,1's,4R,4'R)-4-(3-fluoro-4-(trifluoromethoxy)phenyl)-4'-propyl-1,1'-bi(cyclohexane) is closely related to a steroid core, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(1r,1's,4R,4'R)-4-(3-fluoro-4-(trifluoromethoxy)phenyl)-4'-propyl-1,1'-bi(cyclohexane) (CAS 137810-19-6), molecular formula C22H30F4O and molecular weight 386.47 g/mol, is a CATO reference standard with documented purity and traceability.

(1r,1's,4R,4'R)-4-(3-fluoro-4-(trifluoromethoxy)phenyl)-4'-propyl-1,1'-bi(cyclohexane) (C22H30F4O) contains a steroid core, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

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.
