116440-93-8 - Introduction
2,4,2 '-Trihydroxyazobenzene (or trimethylene) is an organic compound whose chemical formula is C12H11N3O3. The following is a description of the properties, uses, preparation and safety information of the compound:
Nature:
- 2,4,2 '-trihydroxyazobenzene is a yellow crystal or crystalline powder with a melting point of 225-228°C.
-Its molecular structure contains two N = N dipole groups and three hydroxyl groups, which has a strong ability to absorb blue light.
Use:
- 2,4,2 '-trihydroxyazobenzene is an important monovalent cation stabilizer, which can be used in thermal gelling agents, anti-ultraviolet agents and antioxidants.
-It can also be used as a photosensitive dye, laser photo interpretation agent and optical brightener.
Method:
- 2,4,2 '-trihydroxyazobenzene can be synthesized by potassium hydroxide-catalyzed reaction of phenol and nitrous acid to generate resorcinol, and then react with nitric acid to obtain the product.
Safety Information:
- 2,4,2 '-trihydroxyazobenzene is generally relatively safe under normal use conditions, but the following matters still need to be paid attention:
-Avoid inhalation, ingestion and skin contact during operation.
-Avoid violent reactions with strong oxidants, strong acids, etc.
-It should be used in a well-ventilated area and wear personal protective equipment, such as gloves, glasses and protective masks, throughout the entire period.
-For accidental contact or inhalation, rinse with water or seek medical help.
In general, 2,4,2 '-trihydroxyazobenzene is a widely used compound with many uses, but safety protection should be paid attention to during operation.
