C.I.Mordant Red 45 - Introduction
1,2,5-TRIHYDROXYANTHRAQUINONE(1,2,5-TRIHYDROXYANTHRAQUINONE) is an organic compound with the chemical formula C14H8O5. The following is a description of its nature, use, formulation and safety information:
Nature:
1,2,5-TRIHYDROXYANTHRAQUINONE is a dark red to light red solid with a bitter taste. It is sparingly soluble in water and can be dissolved in organic solvents such as ethers, Alcohols, Ketones and aqueous solutions. It is easier to dissolve under acidic conditions.
Use:
1,2,5-TRIHYDROXYANTHRAQUINONE has a wide range of applications in the field of chemistry. It is an important dye and pigment intermediate and is used in the preparation of dyes, inks, coatings, paints and plastics. In addition, it is also used in the preparation of pharmaceuticals and pesticides.
Method:
The preparation method of 1,2,5-TRIHYDROXYANTHRAQUINONE is mainly carried out by nucleophilic substitution reaction of anthracene. Firstly, 2-nitroanthracene was obtained by sulfuric acid nitration catalyzed by sulfuric acid and sulfuric anhydride. Then, by reducing the nitro group, 2-aminoanthracene is obtained. Finally, the oxidation of 2-aminoanthracene under acidic conditions gave 1,2,5-TRIHYDROXYANTHRAQUINONE.
Safety Information:
1,2,5-TRIHYDROXYANTHRAQUINONE has certain toxicity and irritation, should avoid contact with skin, eyes and mouth. Wear appropriate personal protective equipment such as gloves, glasses and masks when used. Good ventilation must be maintained during operation and storage. In addition, the relevant safety procedures should be observed and the requirements of laws and regulations, such as storage, transportation and disposal of waste, should be strictly observed. The safety data sheet of the relevant product should be read and understood carefully before use.
