Chemical Structure
Description
tert-Butyl (2S,4R)-2-({[(4-methylbenzene)sulfonyl]oxy}methyl)-4-(oxan-2-yloxy)pyrrolidine-1-carboxylate (CAS 2140298-83-3) is a high-purity analytical reference standard with the molecular formula C22H33NO7S and a molecular weight of 455.56 g/mol.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, tert-Butyl (2S,4R)-2-({[(4-methylbenzene)sulfonyl]oxy}methyl)-4-(oxan-2-yloxy)pyrrolidine-1-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 455.56 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.
