Chemical Structure
Description
The occurrence of (3R,4S)-4-(2,3-dihydrobenzofuran-5-yl)-2-oxopyrrolidine-3-carboxylic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(3R,4S)-4-(2,3-dihydrobenzofuran-5-yl)-2-oxopyrrolidine-3-carboxylic acid (CAS 1784747-81-4), molecular formula C13H13NO4 and molecular weight 247.25 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, (3R,4S)-4-(2,3-dihydrobenzofuran-5-yl)-2-oxopyrrolidine-3-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 247.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures (3R,4S)-4-(2,3-dihydrobenzofuran-5-yl)-2-oxopyrrolidine-3-carboxylic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
