Description

Compared with other compounds in its class, the molecular weight of 317.21 g/mol gives ethyl 7-(2,4-dichlorophenyl)-7-oxoheptanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies ethyl 7-(2,4-dichlorophenyl)-7-oxoheptanoate (CAS 898778-35-3), a certified reference material (molecular formula C15H18Cl2O3, MW 317.21 g/mol) for analytical method development and quality control.

ethyl 7-(2,4-dichlorophenyl)-7-oxoheptanoate (C15H18Cl2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

As a certified reference material (CRM), ethyl 7-(2,4-dichlorophenyl)-7-oxoheptanoate 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.
