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 3-Benzylidene-5-(5,6,7,8-tetrahydronaphthalen-2-yl)furan-2(3H)-one.
CATO supplies 3-Benzylidene-5-(5,6,7,8-tetrahydronaphthalen-2-yl)furan-2(3H)-one (CAS 6322-96-9), a certified reference material (molecular formula C21H18O2, MW 302.37 g/mol) for analytical method development and quality control.
3-Benzylidene-5-(5,6,7,8-tetrahydronaphthalen-2-yl)furan-2(3H)-one (C21H18O2) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 3-Benzylidene-5-(5,6,7,8-tetrahydronaphthalen-2-yl)furan-2(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.
