Chemical Structure
Description
The occurrence of 4-(1-Methyl-2-oxo-pyrrolidin-3-ylmethyl)-biphenyl-3-carboxylic acid is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-(1-Methyl-2-oxo-pyrrolidin-3-ylmethyl)-biphenyl-3-carboxylic acid (CAS 1361113-74-7), molecular formula C19H19NO3 and molecular weight 309.36 g/mol, is a CATO reference standard with documented purity and traceability.
4-(1-Methyl-2-oxo-pyrrolidin-3-ylmethyl)-biphenyl-3-carboxylic acid (C19H19NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, 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).
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-(1-Methyl-2-oxo-pyrrolidin-3-ylmethyl)-biphenyl-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.
