Description
Compared with other compounds in its class, the molecular weight of 179.64 g/mol gives methyl (3R,4R)-4-methylpyrrolidine-3-carboxylate hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
methyl (3R,4R)-4-methylpyrrolidine-3-carboxylate hydrochloride (CAS 2101775-05-5) is a high-purity analytical reference standard with the molecular formula C7H13NO2HCl and a molecular weight of 179.64 g/mol.
methyl (3R,4R)-4-methylpyrrolidine-3-carboxylate hydrochloride (C7H13NO2HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
