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.
CATO supplies 1,2-Di-m-tolyldisulfane (CAS 20333-41-9), a certified reference material (molecular formula C14H14S2, MW 246.39 g/mol) for analytical method development and quality control.
Owing to sulfur-containing functionality, a polycyclic aromatic system, 1,2-Di-m-tolyldisulfane is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 246.39 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.
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.
