CATO supplies (5-(3,4-Dichlorophenyl)-2,3-dihydro-1H-pyrrolizine-6,7-diyl)bis(methylene) bis(isopropylcarbamate) (CAS 74296-42-7), a certified reference material (molecular formula C23H29Cl2N3O4, MW 482.40 g/mol) for analytical method development and quality control.
The molecular framework of (5-(3,4-Dichlorophenyl)-2,3-dihydro-1H-pyrrolizine-6,7-diyl)bis(methylene) bis(isopropylcarbamate) (C23H29Cl2N3O4) 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. 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.
