For chemists and researchers working with advanced materials, understanding the fundamental properties of the chemicals they use is paramount. 3-Bromofuran, identified by its CAS number 22037-28-1, is a chemical compound that plays a significant role in various synthesis processes, particularly within the electronics and pharmaceutical sectors. This article aims to provide a clear overview of its key characteristics, including its physical state, chemical formula, and important safety considerations.

3-Bromofuran has the molecular formula C4H3BrO and a molecular weight of 146.97. Physically, it is described as a colorless to light yellow liquid. Its density is reported as 1.662 g/cm3, and it has a boiling point of 103°C at standard atmospheric pressure (760 mmHg). These physical properties are crucial for understanding its behavior during reactions and its storage requirements.

A critical aspect of handling 3-Bromofuran is its classification as a flammable liquid and vapor. The Material Safety Data Sheet (MSDS) indicates hazard statements such as H225, meaning it is highly flammable. This necessitates strict adherence to safety protocols to prevent ignition. Precautions like keeping it away from heat, sparks, open flames, and hot surfaces are vital. Proper ventilation in laboratories and manufacturing facilities where 3-Bromofuran is used is also essential to dissipate any potentially flammable vapors and prevent accumulation.

In the context of its applications, 3-Bromofuran is categorized under Electronic Chemicals and Photoresist Chemicals, and also as a Pharmaceutical Material and Fine Chemical. Its role as an intermediate means that it is often used in controlled environments where its reactivity can be harnessed for synthesis. This dual nature – its utility as a building block and its hazardous properties – requires careful management throughout its lifecycle, from procurement from reliable 3-Bromofuran suppliers to its eventual use and disposal.

The synthesis of 3-Bromofuran itself is an important consideration for the chemical industry. Efficient and safe manufacturing processes are key to ensuring a stable supply for the demanding sectors it serves. Understanding the 3-Bromofuran synthesis pathways helps in appreciating the chemical engineering expertise involved in its production.

When procuring 3-Bromofuran, it is important to note that it is typically supplied for professional manufacturing, research laboratories, and industrial/commercial usage only. Companies like CP Lab Chemicals and TCI America offer this compound, often with specific shipping restrictions due to its hazardous nature. The requirement to ship only to U.S. registered laboratories or commercial facilities underscores the need for trained personnel and appropriate infrastructure when handling such chemicals.

In conclusion, while 3-Bromofuran (CAS 22037-28-1) is an invaluable chemical intermediate with significant applications in electronics and pharmaceuticals, its highly flammable nature demands utmost respect and careful handling. By understanding its properties and adhering to rigorous safety guidelines, researchers and manufacturers can effectively leverage its synthetic potential while ensuring a safe working environment.
