Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1,1,2,2-Tetrakis(4-methoxyphenyl)ethene (CAS 10019-24-6), molecular formula C30H28O4 and molecular weight 452.54 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,1,2,2-Tetrakis(4-methoxyphenyl)ethene (C30H28O4) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 1,1,2,2-Tetrakis(4-methoxyphenyl)ethene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
