Chemical Structure
Description
The molecular framework of 4,4'-(Furan-2,5-diyl)bis(N-ethylbenzimidamide) (C22H24N4O) is characterized by a steroid core, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
4,4'-(Furan-2,5-diyl)bis(N-ethylbenzimidamide) (CAS 199919-01-2) is a high-purity analytical reference standard with the molecular formula C22H24N4O and a molecular weight of 360.45 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
