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 (E)-4-(benzo[d][1,3]dioxol-5-yl)-2-(4-methoxystyryl)-5-oxo-5H-indeno[1,2-b]pyridine-3-carbonitrile.
(E)-4-(benzo[d][1,3]dioxol-5-yl)-2-(4-methoxystyryl)-5-oxo-5H-indeno[1,2-b]pyridine-3-carbonitrile (CAS 866142-84-9) is a high-purity analytical reference standard with the molecular formula C29H18N2O4 and a molecular weight of 458.46 g/mol.
The molecular framework of (E)-4-(benzo[d][1,3]dioxol-5-yl)-2-(4-methoxystyryl)-5-oxo-5H-indeno[1,2-b]pyridine-3-carbonitrile (C29H18N2O4) 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 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.
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.
