Chemical Structure

2-Carboethoxy-3-(3-chloro-5-fluorophenyl)propiophenone CAS 898750-31-7 chemical structure

Description

As a certified reference material (CRM), 2-Carboethoxy-3-(3-chloro-5-fluorophenyl)propiophenone 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.

CATO supplies 2-Carboethoxy-3-(3-chloro-5-fluorophenyl)propiophenone (CAS 898750-31-7), a certified reference material (molecular formula C18H16ClFO3, MW 334.77 g/mol) for analytical method development and quality control.

The molecular framework of 2-Carboethoxy-3-(3-chloro-5-fluorophenyl)propiophenone (C18H16ClFO3) 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 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.
