Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Tert-butyl (2s,4r)-2-cyano-4-fluoropyrrolidine-1-carboxylate (CAS 1330286-47-9), molecular formula C10H15FN2O2 and molecular weight 214.24 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Tert-butyl (2s,4r)-2-cyano-4-fluoropyrrolidine-1-carboxylate (C10H15FN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 214.24 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
