Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 284.15 g/mol gives (S)-Benzyl 3-bromopyrrolidine-1-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(S)-Benzyl 3-bromopyrrolidine-1-carboxylate (CAS 1353995-89-7), molecular formula C12H14BrNO2 and molecular weight 284.15 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, (S)-Benzyl 3-bromopyrrolidine-1-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 284.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
