Chemical Structure

3-(4-Chlorophenyl)-2-methoxypropiophenone CAS 898787-62-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 274.74 g/mol gives 3-(4-Chlorophenyl)-2-methoxypropiophenone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-(4-Chlorophenyl)-2-methoxypropiophenone (CAS 898787-62-7), molecular formula C16H15ClO2 and molecular weight 274.74 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-(4-Chlorophenyl)-2-methoxypropiophenone (C16H15ClO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic 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.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
