Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 113.11 g/mol gives Pyrroline-5-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Pyrroline-5-carboxylate (CAS 2139-03-9) is a high-purity analytical reference standard with the molecular formula C5H7NO2 and a molecular weight of 113.11 g/mol.
Pyrroline-5-carboxylate (C5H7NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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 Pyrroline-5-carboxylate 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.
