Chemical Structure
Description
1-(4-Vinylphenyl)-1H-pyrrole-2,5-dione (CAS 19007-91-1), molecular formula C12H9NO2 and molecular weight 199.21 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(4-Vinylphenyl)-1H-pyrrole-2,5-dione (C12H9NO2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1-(4-Vinylphenyl)-1H-pyrrole-2,5-dione meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
