Chemical Structure
Description
The molecular framework of Tris(4-(dimethylamino)phenyl) phosphite (C24H30N3O3P) is characterized by a steroid core, an amide group, a phosphonate group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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).
CATO supplies Tris(4-(dimethylamino)phenyl) phosphite (CAS 41445-40-3), a certified reference material (molecular formula C24H30N3O3P, MW 439.49 g/mol) for analytical method development and quality control.
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), Tris(4-(dimethylamino)phenyl) phosphite 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.
