Chemical Structure
Description
The occurrence of 3-Methyl-1-(phenylsulfanyl)butan-2-one is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Methyl-1-(phenylsulfanyl)butan-2-one (CAS 71221-49-3), molecular formula C11H14OS and molecular weight 194.29 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Methyl-1-(phenylsulfanyl)butan-2-one (C11H14OS) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
