Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-Chloro-3-(2,5-dimethylphenyl)propiophenone (CAS 898753-39-4), 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-Chloro-3-(2,5-dimethylphenyl)propiophenone (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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 4-Chloro-3-(2,5-dimethylphenyl)propiophenone 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.
