Chemical Structure
Description
The occurrence of 7-Chloro-1-(4-fluoro-3-methylphenyl)-1-oxoheptane is closely related to a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
7-Chloro-1-(4-fluoro-3-methylphenyl)-1-oxoheptane (CAS 898761-10-9), molecular formula C14H18ClFO and molecular weight 256.74 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 7-Chloro-1-(4-fluoro-3-methylphenyl)-1-oxoheptane (C14H18ClFO) is characterized by a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. 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), 7-Chloro-1-(4-fluoro-3-methylphenyl)-1-oxoheptane 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.
