Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5'-[(E)-[(2E)-3-[4-(Dimethylamino)phenyl]prop-2-en-1-ylidene]amino]-2'-(furan-2-yl)-[2,3'-bifuran]-4'-carbonitrile.
5'-[(E)-[(2E)-3-[4-(Dimethylamino)phenyl]prop-2-en-1-ylidene]amino]-2'-(furan-2-yl)-[2,3'-bifuran]-4'-carbonitrile (CAS 551930-71-3) is a high-purity analytical reference standard with the molecular formula C24H19N3O3 and a molecular weight of 397.43 g/mol.
The molecular framework of 5'-[(E)-[(2E)-3-[4-(Dimethylamino)phenyl]prop-2-en-1-ylidene]amino]-2'-(furan-2-yl)-[2,3'-bifuran]-4'-carbonitrile (C24H19N3O3) 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. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
