Chemical Structure
Description
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.
(3R,4S)-4-(4-(benzyloxy)-2,6-difluorophenyl)-2-oxopyrrolidine-3-carboxylic acid (CAS 1784748-66-8) is a high-purity analytical reference standard with the molecular formula C18H15F2NO4 and a molecular weight of 347.31 g/mol.
(3R,4S)-4-(4-(benzyloxy)-2,6-difluorophenyl)-2-oxopyrrolidine-3-carboxylic acid (C18H15F2NO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine 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. 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).
As a certified reference material (CRM), (3R,4S)-4-(4-(benzyloxy)-2,6-difluorophenyl)-2-oxopyrrolidine-3-carboxylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
