4-(4-Pentylbicyclo[2.2.2]octan-1-yl)benzoyl chloride (CAS 74446-96-1), molecular formula C20H27ClO and molecular weight 318.88 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(4-Pentylbicyclo[2.2.2]octan-1-yl)benzoyl chloride (C20H27ClO) is characterized by a steroid core, a hydroxyl group, an ether linkage, chlorine 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.
CATO manufactures 4-(4-Pentylbicyclo[2.2.2]octan-1-yl)benzoyl chloride 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.
