Chemical Structure
Description
5-Oxo-1-(thiophen-2-ylmethyl)pyrrolidine-3-carboxylic acid (C10H11NO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
5-Oxo-1-(thiophen-2-ylmethyl)pyrrolidine-3-carboxylic acid (CAS 175136-92-2) is a high-purity analytical reference standard with the molecular formula C10H11NO3S and a molecular weight of 225.26 g/mol.
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.
