1,3-Benzoxazole(CAS: 273-53-0)

1,3-Benzoxazole (CAS: 273-53-0) is a crystalline solid with a molecular weight of approximately 123.14 g/mol. It is slightly soluble in water but more soluble in organic solvents such as ethanol and acetone. Chemically, it is a stable compound with a moderate basicity due to the oxazole ring. It exhibits good thermal stability and is known for its reactivity towards electrophiles and nucleophiles, particularly in the presence of amines and carboxylic acids.

1,3-Benzoxazole can be synthesized via the reaction of benzoyl chloride with hydrazine or its derivatives. A common method involves the condensation of benzoyl chloride with hydrazine hydrate in the presence of a catalyst like p-toluenesulfonic acid. This process yields the 1,3-benzoxazole in good yield, and the method is known for its simplicity and reproducibility.

1,3-Benzoxazole (CAS: 273-53-0) is widely used in various industries. It is a key building block in pharmaceuticals, where it serves as a precursor for drug synthesis. In the polymer industry, it is used in the development of high-performance polymers. It also finds applications in sensors due to its chemical sensing properties and in semiconductors for its electronic properties.

When handling 1,3-Benzoxazole (CAS: 273-53-0), it is crucial to use appropriate personal protective equipment (PPE) such as gloves, goggles, and lab coats. Ensure the work is conducted in a well-ventilated area or a fume hood to minimize exposure. Spills should be cleaned up carefully using appropriate absorbents. Always refer to the Safety Data Sheet (SDS) for detailed handling and disposal instructions to ensure proper safety and compliance with regulations.
