Chemical Structure

1-(4-Chloro-3-fluorophenyl)-3-(3,4-dimethylphenyl)propan-1-one CAS 898779-53-8 chemical structure

Description

The occurrence of 1-(4-Chloro-3-fluorophenyl)-3-(3,4-dimethylphenyl)propan-1-one is closely related to a steroid core, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(4-Chloro-3-fluorophenyl)-3-(3,4-dimethylphenyl)propan-1-one (CAS 898779-53-8), molecular formula C17H16ClFO and molecular weight 290.76 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-(4-Chloro-3-fluorophenyl)-3-(3,4-dimethylphenyl)propan-1-one (C17H16ClFO) is characterized by a steroid core, a hydroxyl group, an ether linkage, fluorine/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), 1-(4-Chloro-3-fluorophenyl)-3-(3,4-dimethylphenyl)propan-1-one 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.
