Chemical Structure

2-Methyl-1-(5-methylthiophen-2-yl)propan-1-one CAS 94199-67-4 chemical structure

Description

2-Methyl-1-(5-methylthiophen-2-yl)propan-1-one (CAS 94199-67-4), molecular formula C9H12OS and molecular weight 168.26 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-Methyl-1-(5-methylthiophen-2-yl)propan-1-one (C9H12OS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 168.26 g/mol, it falls into the medium-molecular-weight range. 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.
