3,4-Dimethylphenylmethylsulfoxide CAS 38417-53-7 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

3,4-Dimethylphenylmethylsulfoxide (CAS 38417-53-7), molecular formula C9H12OS and molecular weight 168.26 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3,4-Dimethylphenylmethylsulfoxide (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).

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.
