2-Carboethoxy-3-(3-methylphenyl)propiophenone CAS 898790-49-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Carboethoxy-3-(3-methylphenyl)propiophenone.

2-Carboethoxy-3-(3-methylphenyl)propiophenone (CAS 898790-49-3) is a high-purity analytical reference standard with the molecular formula C19H20O3 and a molecular weight of 296.36 g/mol.

The molecular framework of 2-Carboethoxy-3-(3-methylphenyl)propiophenone (C19H20O3) is characterized by a steroid core, a hydroxyl group, an ether linkage. 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.

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.
