Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2S)-4-Fluoro-5-oxopyrrolidine-2-carboxylic acid.
(2S)-4-Fluoro-5-oxopyrrolidine-2-carboxylic acid (CAS 958220-22-9), molecular formula C5H6FNO3 and molecular weight 147.10 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2S)-4-Fluoro-5-oxopyrrolidine-2-carboxylic acid (C5H6FNO3) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
CATO manufactures (2S)-4-Fluoro-5-oxopyrrolidine-2-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.
