Chemical Structure
Description
(4-Butylphenyl)(4-chlorophenyl)methanone (CAS 64357-64-8), molecular formula C17H17ClO and molecular weight 272.77 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (4-Butylphenyl)(4-chlorophenyl)methanone (C17H17ClO) 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (4-Butylphenyl)(4-chlorophenyl)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.
