Description
CATO supplies 1-Bis[3-(trifluoromethyl)phenoxy]phosphoryl-4-(3-chlorophenoxy)benzene (CAS 74038-37-2), a certified reference material (molecular formula C26H16ClF6O4P, MW 572.82 g/mol) for analytical method development and quality control.
Structurally, 1-Bis[3-(trifluoromethyl)phenoxy]phosphoryl-4-(3-chlorophenoxy)benzene (C26H16ClF6O4P) contains a steroid core, a phosphate ester group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.5, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 572.82 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.
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.
As a certified reference material (CRM), 1-Bis[3-(trifluoromethyl)phenoxy]phosphoryl-4-(3-chlorophenoxy)benzene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
