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)-2-((4-methoxybenzylidene)amino)-5-phenylfuran-3-carbonitrile.
(E)-2-((4-methoxybenzylidene)amino)-5-phenylfuran-3-carbonitrile (CAS 325809-24-3) is a high-purity analytical reference standard with the molecular formula C19H14N2O2 and a molecular weight of 302.33 g/mol.
The molecular framework of (E)-2-((4-methoxybenzylidene)amino)-5-phenylfuran-3-carbonitrile (C19H14N2O2) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
