4-Hydroxy-2,6-bis(tris(4-(tert-butyl)phenyl)silyl)dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepine 4-oxide CAS 1155899-63-0

Description

As a certified reference material (CRM), 4-Hydroxy-2,6-bis(tris(4-(tert-butyl)phenyl)silyl)dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepine 4-oxide 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.

4-Hydroxy-2,6-bis(tris(4-(tert-butyl)phenyl)silyl)dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepine 4-oxide (CAS 1155899-63-0), molecular formula C80H89O4PSi2 and molecular weight 1201.71 g/mol, is a CATO reference standard with documented purity and traceability.

4-Hydroxy-2,6-bis(tris(4-(tert-butyl)phenyl)silyl)dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepine 4-oxide (C80H89O4PSi2) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
