Chemical Structure

Tris(p-isocyanatophenyl)amine CAS 19759-70-7 chemical structure

Description

The occurrence of Tris(p-isocyanatophenyl)amine is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Tris(p-isocyanatophenyl)amine (CAS 19759-70-7) is a high-purity analytical reference standard with the molecular formula C21H12N4O3 and a molecular weight of 368.34 g/mol.

Structurally, Tris(p-isocyanatophenyl)amine (C21H12N4O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 18.0, corresponding to approximately 18 ring(s) or double-bond equivalent(s). With a molecular weight of 368.34 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
