Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 205.68 g/mol gives (R)-tert-Butyl 3-chloropyrrolidine-1-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(R)-tert-Butyl 3-chloropyrrolidine-1-carboxylate (CAS 1289585-27-8), molecular formula C9H16ClNO2 and molecular weight 205.68 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (R)-tert-Butyl 3-chloropyrrolidine-1-carboxylate (C9H16ClNO2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
