Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 429.66 g/mol gives 3-(3-Nitrobenzylidene)pyrrolidin-2-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-(3-Nitrobenzylidene)pyrrolidin-2-one (CAS 53031-76-8), molecular formula C18H30O3SC4H13N3 and molecular weight 429.66 g/mol, is a CATO reference standard with documented purity and traceability.
3-(3-Nitrobenzylidene)pyrrolidin-2-one (C18H30O3SC4H13N3) contains an amide group, a sulfone group, a carboxylic acid 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 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 3-(3-Nitrobenzylidene)pyrrolidin-2-one 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.
