Chemical Structure
Description
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, (S)-1-tert-Butyl 3-methyl 3-(methylthio)pyrrolidine-1,3-dicarboxylate is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 275.36 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)-1-tert-Butyl 3-methyl 3-(methylthio)pyrrolidine-1,3-dicarboxylate (CAS 1093063-63-8), molecular formula C12H21NO4S and molecular weight 275.36 g/mol, is a CATO reference standard with documented purity and traceability.
