Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 341.49 g/mol gives [1-((S)-2-Amino-3-methyl-butyryl)-pyrrolidin-3-ylmethyl]-isopropyl-carbamic acid tert-butyl ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
[1-((S)-2-Amino-3-methyl-butyryl)-pyrrolidin-3-ylmethyl]-isopropyl-carbamic acid tert-butyl ester (CAS 1354029-25-6) is a high-purity analytical reference standard with the molecular formula C18H35N3O3 and a molecular weight of 341.49 g/mol.
[1-((S)-2-Amino-3-methyl-butyryl)-pyrrolidin-3-ylmethyl]-isopropyl-carbamic acid tert-butyl ester (C18H35N3O3) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
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.
