13224-79-8 - Introduction

3,3 ',4,4'-Tetraaminodiphenyl sulfone (TAD) is an organic substance with the following properties:

1. Appearance: TAD is a colorless to light yellow crystalline solid.
2. Solubility: TAD has low solubility in common organic solvents.

TAD has several applications:

1. Dye intermediate: It is often used as a dye synthesis intermediate, especially as a molecular regulator, which can be used in the preparation of organic dyes.
2. Electronic materials: TAD has application potential in organic optoelectronic devices, and can be used in organic light-emitting diodes (OLED) and organic solar cells.
3. Chemical analysis: TAD can also be used as a redox indicator in chemical analysis.

Preparation of TAD:

TAD can be prepared by the reaction of dinitrodiphenyl sulfone and ammonia. First, dinitrodiphenyl sulfone is reacted with ammonia in an appropriate solvent, and after appropriate treatment and crystallization, the pure TAD product is obtained.

About safety information:

1. toxicity: TAD has certain toxicity to human body and environment. Avoid inhalation, contact with skin or ingestion during handling and storage.
2. Explosion hazard: TAD is a combustible solid, which will burn when heated or exposed to an open flame and produce toxic gases.
3. Storage precautions: TAD should be stored in a sealed container, away from fire and oxidant. At the same time, to avoid contact with acidic and alkaline substances.

When handling TAD, follow safe practices and follow relevant laboratory safety guidelines.
