Chemical Structure

3-(4-Chloro-phenyl)-3-oxo-propionic acid methylester CAS 676348-64-4 chemical structure

Description

Structurally, 3-(4-Chloro-phenyl)-3-oxo-propionic acid methylester (C12H14O5) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 238.24 g/mol, it falls into the medium-molecular-weight range. 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).

3-(4-Chloro-phenyl)-3-oxo-propionic acid methylester (CAS 676348-64-4) is a high-purity analytical reference standard with the molecular formula C12H14O5 and a molecular weight of 238.24 g/mol.

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.
