Chemical Structure

2-Methyl-1-phenylbutan-1-one CAS 938-87-4 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.

CATO supplies 2-Methyl-1-phenylbutan-1-one (CAS 938-87-4), a certified reference material (molecular formula C11H14O, MW 162.23 g/mol) for analytical method development and quality control.

Structurally, 2-Methyl-1-phenylbutan-1-one (C11H14O) contains a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 162.23 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
