DIAZO REAGENT OA - Introduction
Fixiu B salt, also known as crystal violet, is an organic dye. The following is the introduction of the nature, use, preparation method and safety information of the solid purple B salt:
Nature:
The solid violet B salt is a deep purple crystalline solid. It is soluble in water and alcohol and has good dyeing properties. Under acidic conditions, its solubility is high, while under alkaline conditions, it is prone to photolysis.
Use:
1. solid violet B salt is widely used in the dye industry, especially for the dyeing of cotton fibers.
2. It is also used as a staining reagent for biochemical experiments and can be used to stain cellular nucleic acids and proteins.
3. The solid violet B salt is also used as a stain under the biological microscope, and has certain applications in histological research and medical diagnosis.
Preparation Method:
The preparation method of solid violet B salt is usually by adding nitrated soda or sodium hydroxide to a phenol solution of phenol, and then adding sulfuric acid to dehydrate it to obtain crystalline solid violet B salt.
Safety Information:
1. solid violet B salt is an organic dye, which is relatively stable, but it is easy to photolysis under alkaline conditions, so it is necessary to avoid prolonged exposure to alkaline environment.
2. Wear appropriate protective gloves and goggles to avoid contact with skin and eyes when carrying, storing and handling solid purple B salt.
3. If the solid purple B salt is swallowed, drink plenty of water immediately and seek medical help.
4. Waste liquid and solid solid violet B salt should be disposed of in accordance with local pollution treatment regulations to prevent negative impact on the environment.
