2,5-Dimethylphenyl ethyl sulfide CAS 158321-96-1

Description

2,5-Dimethylphenyl ethyl sulfide (CAS 158321-96-1), molecular formula C10H14S and molecular weight 166.28 g/mol, is a CATO reference standard with documented purity and traceability.

2,5-Dimethylphenyl ethyl sulfide (C10H14S) contains sulfur-containing functionality, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
