Chemical Structure

2-Methyl-1-[4-(1-methylethyl)phenyl]-1-propanone CAS 72846-62-9 chemical structure

Description

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.

2-Methyl-1-[4-(1-methylethyl)phenyl]-1-propanone (CAS 72846-62-9), molecular formula C13H18O and molecular weight 190.28 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Methyl-1-[4-(1-methylethyl)phenyl]-1-propanone (C13H18O) is characterized by a hydroxyl group, an ether linkage, an aromatic ring 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 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).

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.
