Chemical Structure
Description
The occurrence of Tetrakis(4-hydroxyphenyl)ethylene is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Tetrakis(4-hydroxyphenyl)ethylene (CAS 119301-59-6), molecular formula C26H20O4 and molecular weight 396.43 g/mol, is a CATO reference standard with documented purity and traceability.
Tetrakis(4-hydroxyphenyl)ethylene (C26H20O4) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 Tetrakis(4-hydroxyphenyl)ethylene 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.
