128915-86-6 - Introduction
3,4,5, is an organic compound. The following is a description of the nature, use, method and safety information:
Nature:
-Appearance: 3,4,5, red crystals or powder.
-Solubility: It has better solubility in organic solvents, but lower solubility in water.
- pH indicator: It is an acid-base indicator with a color range of red to yellow.
-Thermal stability: It has a certain thermal stability at high temperatures.
Use:
-Acid-base indicator: 3,4,5, widely used as acid-base indicator, can be used to determine the acid-base properties and pH value of the solution.
-Laboratory applications: It can also be used for color indicators, catalysts and spectral analysis in chemical laboratories.
Preparation Method:
- 3,4,5, benzenesulfonyl chloride is usually synthesized by reacting 3,4,5,6-tetrabromophenol with benzenesulfonyl chloride. This reaction produces a phthalein ring and a bromine atom replaces the hydrogen atom on the benzene ring.
-The synthesis method can be improved and optimized according to specific experimental conditions and uses.
Safety Information:
- 3,4,5, in general, non-toxic to the human body.
-However, it may cause irritation to the eyes and skin. Therefore, when handling, wear appropriate personal protective equipment to avoid direct contact.
-During storage and use, avoid contact with oxidants and strong acids to avoid dangerous chemical reactions.
