Chemical Structure
Description
4-Benzylidene-2,6-di-tert-butylcyclohexa-2,5-dien-1-one (C21H26O) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
4-Benzylidene-2,6-di-tert-butylcyclohexa-2,5-dien-1-one (CAS 7078-98-0), molecular formula C21H26O and molecular weight 294.43 g/mol, is a CATO reference standard with documented purity and traceability.
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-Benzylidene-2,6-di-tert-butylcyclohexa-2,5-dien-1-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.
