Chemical Structure
Description
The occurrence of (2R,3R)-3-Methoxy-2-methyl-3-((S)-pyrrolidin-2-yl)propanoic acid hydrochloride is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (2R,3R)-3-Methoxy-2-methyl-3-((S)-pyrrolidin-2-yl)propanoic acid hydrochloride (CAS 1438852-11-9), a certified reference material (molecular formula C9H17NO3HCl, MW 223.70 g/mol) for analytical method development and quality control.
(2R,3R)-3-Methoxy-2-methyl-3-((S)-pyrrolidin-2-yl)propanoic acid hydrochloride (C9H17NO3HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
