Chemical Structure

1-((2,5-Dimethylphenyl)thio)butan-2-one CAS 1249155-59-6 chemical structure

Description

CATO supplies 1-((2,5-Dimethylphenyl)thio)butan-2-one (CAS 1249155-59-6), a certified reference material (molecular formula C12H16OS, MW 208.32 g/mol) for analytical method development and quality control.

The molecular framework of 1-((2,5-Dimethylphenyl)thio)butan-2-one (C12H16OS) is characterized by sulfur-containing functionality, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
