1,5-dibromonaphthalene - Risk and Safety
1,5-dibromonaphthalene - Introduction
1,5-dibromonaphthalene(1,5-dibromonaphthalene) is an organic compound with the chemical formula C10H6Br2. The following is a description of some properties, uses, methods and safety information about 1,5-dibromonaphthalene:
Nature:
1,5-dibromonaphthalene is a colorless to light yellow crystal with a special aromatic odor. Its density is relatively high, with a melting point of 80-81°C and a boiling point of 327°C. The compound is poorly soluble in water and is soluble in most organic solvents, such as ethanol, dimethyl sulfoxide and methylene chloride.
Use:
1,5-dibromonaphthalene is an important organic synthesis intermediate, widely used in organic synthesis and materials science. It can be used as a starting material for dye synthesis, pharmaceutical synthesis and liquid crystal materials. In addition, 1,5-dibromonaphthalene can also be used for the preparation of optical brilliant blue fluorescent dyes and brominated amino ketones and other organic compounds.
Preparation Method:
There are many ways to prepare 1,5-dibromonaphthalene. A common method is to react 1,5-dichloronaphthalene with a metal bromide (such as bromine or ferric tribromide) in an organic solvent to form 1,5-dibromonaphthalene. In addition, 1,5-dihydroxynaphthalene can also be prepared by a bromination reaction.
Safety Information:
1,5-dibromonaphthalene is dangerous. It can cause eye, skin and respiratory tract irritation. Wear appropriate protective equipment such as chemical protective gloves, goggles, and respiratory protective equipment during operation. Avoid prolonged inhalation or contact with the substance. 1,5-dibromonaphthalene should be stored and handled properly and relevant safe operating procedures should be followed. Before use, it is recommended to read the product safety data form (SDS) carefully and follow the relevant safety instructions.
