Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
8-Methoxy-4-oxo-1,4-dihydroquinoline-3-carbonitrile (CAS 71083-71-1) is a high-purity analytical reference standard with the molecular formula C11H8N2O2 and a molecular weight of 200.19 g/mol.
The molecular framework of 8-Methoxy-4-oxo-1,4-dihydroquinoline-3-carbonitrile (C11H8N2O2) is characterized by an amino-acid-derived structure, 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.
CATO manufactures 8-Methoxy-4-oxo-1,4-dihydroquinoline-3-carbonitrile under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
