FAQ

What are the physical and chemical properties of 2,4-Dibromopyridine 1-oxide (CAS: 117196-08-4)?

2,4-Dibromopyridine 1-oxide (CAS: 117196-08-4) is a solid with a crystalline form. Its molecular weight is approximately 270.04 g/mol. It has a low solubility in water but is more soluble in organic solvents such as dimethylformamide and acetonitrile. Chemically, it is less reactive than many other derivatives of pyridine due to the electron-withdrawing bromine atoms, which stabilize the positive charge on the nitrogen atom. It is stable under normal conditions but should be stored in a dry place away from moisture.

How is 2,4-Dibromopyridine 1-oxide (CAS: 117196-08-4) typically synthesized?

2,4-Dibromopyridine 1-oxide (CAS: 117196-08-4) is typically synthesized by the reaction of 2,4-dibromopyridine with a suitable oxidizing agent, such as potassium permanganate or potassium dichromate, in an aqueous medium. The reaction is selective and yields the 1-oxide product with high purity. The yield is generally around 85-90%, depending on the purity of the starting material and the reaction conditions.

What industries use 2,4-Dibromopyridine 1-oxide (CAS: 117196-08-4)?

2,4-Dibromopyridine 1-oxide (CAS: 117196-08-4) is used in the pharmaceutical industry for the synthesis of certain drugs, particularly those involving pyridine derivatives. It is also used in the polymer industry as a precursor for the preparation of functionalized polymers, and in the semiconductor industry as a precursor for the fabrication of organic semiconductor materials. Additionally, it is used in the sensor industry for the development of gas sensors and other electronic sensors.

What precautions should be taken when handling 2,4-Dibromopyridine 1-oxide (CAS: 117196-08-4)?

When handling 2,4-Dibromopyridine 1-oxide (CAS: 117196-08-4), it is important to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. It should be handled in a well-ventilated area or a fume hood to minimize inhalation risks. Spills should be cleaned up carefully using appropriate absorbent materials and disposing of the waste according to local regulations. Always refer to the Safety Data Sheet (SDS) for detailed guidance on safe handling and storage.
