Basic Information and Parameters

Benzofuran, with the CAS number 271 - 89 - 6, is an important heterocyclic compound. It has a molecular formula of (C_8H_6O) and a molecular weight of approximately 118.13 g/mol. Benzofuran appears as a colorless to pale - yellow liquid under normal conditions. It has a boiling point around 175 - 176°C and a melting point of - 18°C. Its density is about 1.095 g/mL at 25°C. It is insoluble in water but soluble in common organic solvents such as ethanol, ether, and chloroform. The chemical structure of benzofuran consists of a benzene ring fused to a furan ring, which endows it with unique chemical properties.

Uses of Benzofuran

Benzofuran has a wide range of applications in various fields. In the pharmaceutical industry, it serves as a key intermediate in the synthesis of numerous drugs. Many benzofuran - containing drugs have shown significant biological activities, such as anti - inflammatory, anti - tumor, and anti - microbial properties. For example, some benzofuran derivatives can be used to develop new drugs for the treatment of cancer by inhibiting the growth of tumor cells.

In the field of organic synthesis, benzofuran is used as a building block. It can participate in a variety of chemical reactions, such as electrophilic substitution reactions, nucleophilic addition reactions, and cycloaddition reactions, to synthesize more complex organic compounds. These compounds are used in the production of dyes, perfumes, and advanced materials.

How to Use Benzofuran

When using benzofuran in a laboratory or industrial setting, strict safety precautions should be taken. First of all, it should be used in a well - ventilated area, preferably in a fume hood. Personal protective equipment, including gloves, goggles, and a lab coat, should be worn to prevent direct contact with the skin and eyes.

In chemical reactions, the appropriate reaction conditions need to be carefully selected according to the specific reaction type. For example, in electrophilic substitution reactions, the reaction temperature, reaction time, and the type of catalyst all need to be optimized to ensure high reaction efficiency and product yield. When handling benzofuran, it should be stored in a cool, dry place away from heat sources and oxidizing agents to prevent decomposition and potential fire hazards.

Usage Cases

Case 1: Pharmaceutical Research and Development

A research team in a pharmaceutical company was working on developing a new anti - inflammatory drug. They used benzofuran as a starting material. By a series of chemical reactions, they introduced different functional groups to the benzofuran structure. After multiple rounds of screening and optimization, they finally obtained a benzofuran - based compound with excellent anti - inflammatory activity. In pre - clinical trials, this compound significantly reduced the inflammation in test animals, showing great potential for further development into a new anti - inflammatory drug.

Case 2: Organic Dye Synthesis

In a dye manufacturing factory, benzofuran was used in the synthesis of a new type of fluorescent dye. Through a cycloaddition reaction, benzofuran was combined with other aromatic compounds. The resulting dye had strong fluorescence properties, high stability, and good solubility in organic solvents. This dye was widely used in the textile industry for fabric dyeing, as it could produce bright and long - lasting colors.
