3-Bromo-2-fluoro-5-methylpyridine（CAS# 17282-01-8) Introduction
is a colorless to pale yellow liquid. It has a pungent odor at room temperature. The density of the compound is higher, and its melting point and boiling point increase with the increase of bromine content.
Use:
It is mainly used as a reagent or intermediate in organic synthesis. It can be used in the preparation of pharmaceuticals, pesticides and other organic compounds. It can also be used as a reagent in research and laboratories.
Method:
The method of preparing the pill mainly includes a two-step reaction. First, bromomethylpyridine is reacted with potassium fluoride in an organic solvent to introduce a fluorine atom. The resulting bromofluoro compound is then oxidized to the corresponding halogen with hydrogen peroxide or other oxidizing agents.
Safety Information:
It is an organic compound and should be handled with care. During use or preparation, appropriate safety measures should be taken, such as wearing chemical protective gloves, goggles and exhaust systems outside the laboratory. Avoid contact with skin and eyes, and keep away from fire. When storing, keep the container sealed and place it in a cool, dry place. In case of ingestion or skin contact, seek medical attention immediately.
