Chemical Structure
Description
4-Oxo-4-pyrrolidin-1-ylbutanoic acid (CAS 69338-35-8) is a high-purity analytical reference standard with the molecular formula C8H13NO3 and a molecular weight of 171.19 g/mol.
4-Oxo-4-pyrrolidin-1-ylbutanoic acid (C8H13NO3) contains an amino-acid-derived structure, an amide 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 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 4-Oxo-4-pyrrolidin-1-ylbutanoic 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.
