Chemical Structure
Description
Structurally, (S)-(4-Methylenepyrrolidin-2-yl)methyl acetate 2,2,2-trifluoroacetate (C8H13NO2C2HF3O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 269.22 g/mol, it falls into the medium-molecular-weight range. 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).
(S)-(4-Methylenepyrrolidin-2-yl)methyl acetate 2,2,2-trifluoroacetate (CAS 1956434-89-1), molecular formula C8H13NO2C2HF3O2 and molecular weight 269.22 g/mol, is a CATO reference standard with documented purity and traceability.
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.
