Chemical Structure
Description
The occurrence of (R)-Methyl 2-(pyrrolidin-3-yloxy)acetate 4-methylbenzenesulfonate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(R)-Methyl 2-(pyrrolidin-3-yloxy)acetate 4-methylbenzenesulfonate (CAS 1965314-51-5) is a high-purity analytical reference standard with the molecular formula C7H8O3SC7H13NO3 and a molecular weight of 331.38 g/mol.
(R)-Methyl 2-(pyrrolidin-3-yloxy)acetate 4-methylbenzenesulfonate (C7H8O3SC7H13NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
