(R)-2-Bromo-7-((tert-butyldiphenylsilyl)oxy)hept-1-en-4-yl 4-methylbenzenesulfonate (CAS 871355-80-5), molecular formula C30H37BrO4SSi and molecular weight 601.67 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution, (R)-2-Bromo-7-((tert-butyldiphenylsilyl)oxy)hept-1-en-4-yl 4-methylbenzenesulfonate is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 601.67 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
