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.
1-Octyl-5-oxopyrrolidine-3-carboxylic acid (CAS 58505-91-2), molecular formula C22H29NO and molecular weight 323.47 g/mol, is a CATO reference standard with documented purity and traceability.
1-Octyl-5-oxopyrrolidine-3-carboxylic acid (C22H29NO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 1-Octyl-5-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.
