Chemical Structure

Ethyl 2-(3-(4-chlorophenyl)propanoyl)benzoate CAS 898787-72-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 316.78 g/mol gives Ethyl 2-(3-(4-chlorophenyl)propanoyl)benzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ethyl 2-(3-(4-chlorophenyl)propanoyl)benzoate (CAS 898787-72-9), molecular formula C18H17ClO3 and molecular weight 316.78 g/mol, is a CATO reference standard with documented purity and traceability.

Ethyl 2-(3-(4-chlorophenyl)propanoyl)benzoate (C18H17ClO3) contains a steroid core, a hydroxyl group, an ether linkage, chlorine substitution. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 2-(3-(4-chlorophenyl)propanoyl)benzoate 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.
