Chemical Structure
Description
Owing to a steroid core, a sulfone group, a hydroxyl group, an ether linkage, S-(2-hydroxyethyl) 4-(5,5-diethyl-1,3-dioxan-2-yl)benzothioate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 324.44 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
S-(2-hydroxyethyl) 4-(5,5-diethyl-1,3-dioxan-2-yl)benzothioate (CAS 1569627-69-5), molecular formula C17H24O4S and molecular weight 324.44 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
