Solvent Blue 74 - Introduction
Solvent Blue 74 is an organic dye with the chemical name 1-(4-(Cyclohexylamino)-3-nitrophenyl)-3-(4-sulfophenyl)triaz-1-en-2-ol, usually expressed by its chemical structure. It is a powdery substance with a bright blue color. Solvent Blue 74 is soluble in water, but more soluble in organic solvents, so it is widely used as an organic Solvent dye.
Solvent Blue 74 has good temperature resistance and light resistance, so it is often used in the coloring of industrial products such as Inks, plastics, coatings and paints. It can give the product a full, bright blue. Solvent Blue 74 is also used in the formulation of certain pigments and dye oils.
in the preparation method, Solvent Blue 74 can obtain nitroso compound by reacting nitrous acid with aniline, then react with phenol with substituent at para position, and finally obtain the target product through acetylation and sulfonation.
For safety information, Solvent Blue 74 is toxic and should be avoided by inhalation, ingestion or contact with skin. During use, the respiratory tract, skin and eyes should be protected at the same time to avoid dust. If inadvertent contact, should be promptly washed with water. In addition, Solvent Blue 74 should also be kept away from fire and high temperature environment, stored in a cool, dry place, away from open flame and heat source. In the use and storage process, should follow the relevant safety procedures.
