Chemical Structure
Description
Tert-butyl (3R,4S)-3-(4-bromophenyl)-4-(hydroxymethyl)pyrrolidine-1-carboxylate (CAS 2242895-39-0), molecular formula C16H22BrNO3 and molecular weight 356.25 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution, Tert-butyl (3R,4S)-3-(4-bromophenyl)-4-(hydroxymethyl)pyrrolidine-1-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 356.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
