Chemical Structure
Description
The molecular framework of Phosphoric Acid Tris(4-methylphenyl)-d21 Ester (C21D21O4P) is characterized by deuterium isotope labeling, a flavonoid 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Phosphoric Acid Tris(4-methylphenyl)-d21 Ester (CAS 2469244-63-9) is a high-purity analytical reference standard with the molecular formula C21D21O4P and a molecular weight of 389.49 g/mol.
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), Phosphoric Acid Tris(4-methylphenyl)-d21 Ester 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.
