Chemical Structure
Description
CATO supplies 4-[(E)-2-(4-Nitrophenyl)vinyl]pyridine (CAS 7372-12-5), a certified reference material (molecular formula C13H10N2O2, MW 226.23 g/mol) for analytical method development and quality control.
The molecular framework of 4-[(E)-2-(4-Nitrophenyl)vinyl]pyridine (C13H10N2O2) is characterized by a nitrogen-containing heterocyclic scaffold, 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.
