Chemical Structure
Description
Owing to sulfur-containing functionality, 3,3,7,7,11,11,15,15-Octamethyl-1,5,9,13-tetrathiacyclohexadecane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 408.79 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.
3,3,7,7,11,11,15,15-Octamethyl-1,5,9,13-tetrathiacyclohexadecane (CAS 110935-37-0), molecular formula C20H40S4 and molecular weight 408.79 g/mol, is a CATO reference standard with documented purity and traceability.
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.
