Chemical Structure
Description
Dimethyl 5-(3,4-dichlorophenyl)-2,3-dihydro-1H-pyrrolizine-6,7-dicarboxylate (CAS 62522-87-6) is a high-purity analytical reference standard with the molecular formula C17H15Cl2NO4 and a molecular weight of 368.21 g/mol.
The molecular framework of Dimethyl 5-(3,4-dichlorophenyl)-2,3-dihydro-1H-pyrrolizine-6,7-dicarboxylate (C17H15Cl2NO4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), Dimethyl 5-(3,4-dichlorophenyl)-2,3-dihydro-1H-pyrrolizine-6,7-dicarboxylate 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.
