Chemical Structure
Description
CATO supplies 1-(2-Methylphenyl)-3,3-bis(methylsulfanyl)prop-2-en-1-one (CAS 56944-66-2), a certified reference material (molecular formula C12H14OS2, MW 238.37 g/mol) for analytical method development and quality control.
1-(2-Methylphenyl)-3,3-bis(methylsulfanyl)prop-2-en-1-one (C12H14OS2) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, 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.
