Chemical Structure
Description
CATO supplies 4-tert-Butyl-3-chloro-4-fluorobenzophenone (CAS 951890-25-8), a certified reference material (molecular formula C17H16ClFO, MW 290.76 g/mol) for analytical method development and quality control.
4-tert-Butyl-3-chloro-4-fluorobenzophenone (C17H16ClFO) contains a steroid core, a hydroxyl group, an ether linkage, fluorine/chlorine 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.
CATO manufactures 4-tert-Butyl-3-chloro-4-fluorobenzophenone under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
