Chemical Structure
Description
4,6-Dimethoxy-2-methyl-3-(naphthalen-1-yl)benzofuran (CAS 922140-84-9) is a high-purity analytical reference standard with the molecular formula C21H18O3 and a molecular weight of 318.37 g/mol.
The molecular framework of 4,6-Dimethoxy-2-methyl-3-(naphthalen-1-yl)benzofuran (C21H18O3) is characterized by a steroid core, 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 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 4,6-Dimethoxy-2-methyl-3-(naphthalen-1-yl)benzofuran 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.
