3-(3,5-Dimethylphenyl)-2-fluoropropiophenone CAS 898780-82-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(3,5-Dimethylphenyl)-2-fluoropropiophenone.

3-(3,5-Dimethylphenyl)-2-fluoropropiophenone (CAS 898780-82-0) is a high-purity analytical reference standard with the molecular formula C17H17FO and a molecular weight of 256.31 g/mol.

The molecular framework of 3-(3,5-Dimethylphenyl)-2-fluoropropiophenone (C17H17FO) is characterized by a steroid core, a hydroxyl group, an ether linkage, fluorine 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 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.
