Chemical Structure

Tris(4-nitrophenyl) phosphate CAS 3871-20-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Tris(4-nitrophenyl) phosphate.

Tris(4-nitrophenyl) phosphate (CAS 3871-20-3), molecular formula C18H12N3O10P and molecular weight 461.28 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Tris(4-nitrophenyl) phosphate (C18H12N3O10P) is characterized by a flavonoid core, an amide group, a phosphate ester 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).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
