Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Methyl-3-phenyl-2,5-dihydro-1H-pyrrole oxalate.
1-Methyl-3-phenyl-2,5-dihydro-1H-pyrrole oxalate (CAS 97382-81-5) is a high-purity analytical reference standard with the molecular formula C11H13NC2H2O4 and a molecular weight of 249.27 g/mol.
The molecular framework of 1-Methyl-3-phenyl-2,5-dihydro-1H-pyrrole oxalate (C11H13NC2H2O4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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-Methyl-3-phenyl-2,5-dihydro-1H-pyrrole oxalate 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.
