Chemical Structure
Description
The occurrence of (4-(Tert-butyl)phenyl)(3,5-difluorophenyl)methanone 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.
(4-(Tert-butyl)phenyl)(3,5-difluorophenyl)methanone (CAS 844885-10-5), molecular formula C17H16F2O and molecular weight 274.31 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (4-(Tert-butyl)phenyl)(3,5-difluorophenyl)methanone (C17H16F2O) is characterized by a steroid core, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
As a certified reference material (CRM), (4-(Tert-butyl)phenyl)(3,5-difluorophenyl)methanone 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.
