1,4-didodecyl 2-sulfanylbutanedioate (CAS 63979-81-7) is a high-purity analytical reference standard with the molecular formula C28H54O4S and a molecular weight of 486.79 g/mol.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 1,4-didodecyl 2-sulfanylbutanedioate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 486.79 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.
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.
