Chemical Structure
Description
Hexadecyl Diphenyl Phosphate (CAS 56827-92-0), molecular formula C28H43O4P and molecular weight 474.61 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Hexadecyl Diphenyl Phosphate (C28H43O4P) is characterized by a steroid core, a phosphate ester group, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Hexadecyl Diphenyl Phosphate 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.
