Ethyl 7-(2-chlorophenyl)-7-oxoheptanoate CAS 898759-07-4

Description

The occurrence of Ethyl 7-(2-chlorophenyl)-7-oxoheptanoate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ethyl 7-(2-chlorophenyl)-7-oxoheptanoate (CAS 898759-07-4), molecular formula C15H19ClO3 and molecular weight 282.76 g/mol, is a CATO reference standard with documented purity and traceability.

Ethyl 7-(2-chlorophenyl)-7-oxoheptanoate (C15H19ClO3) 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-chlorophenyl)-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.
