4-[2-(2-Oxo-pyrrolidin-1-yl)-ethoxy]-benzoic acid CAS 215656-70-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-[2-(2-Oxo-pyrrolidin-1-yl)-ethoxy]-benzoic acid.

4-[2-(2-Oxo-pyrrolidin-1-yl)-ethoxy]-benzoic acid (CAS 215656-70-5) is a high-purity analytical reference standard with the molecular formula C13H15NO4 and a molecular weight of 249.26 g/mol.

4-[2-(2-Oxo-pyrrolidin-1-yl)-ethoxy]-benzoic acid (C13H15NO4) contains a nitrogen-containing heterocyclic scaffold, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

CATO manufactures 4-[2-(2-Oxo-pyrrolidin-1-yl)-ethoxy]-benzoic 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.
