Chemical Structure
Description
Cis-2,6-bis(4-methoxyphenyl)dihydro-2H-selenopyran-4(3H)-one (CAS 54232-40-5) is a high-purity analytical reference standard with the molecular formula C19H20O3Se and a molecular weight of 375.32 g/mol.
Owing to a steroid core, a hydroxyl group, an ether linkage, Cis-2,6-bis(4-methoxyphenyl)dihydro-2H-selenopyran-4(3H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 375.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures Cis-2,6-bis(4-methoxyphenyl)dihydro-2H-selenopyran-4(3H)-one 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.
