Chemical Structure
Description
4-Methyl-2-[(4-methylphenyl)sulfanyl]quinoline (CAS 64789-02-2), molecular formula C17H15NS and molecular weight 265.37 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 4-Methyl-2-[(4-methylphenyl)sulfanyl]quinoline is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 265.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
