[5-bromo-3- [(1R) – (2,6-dichloro-3-fluorophenyl) ethoxy] pyridin-2-yl] amine, commonly known as BPA, is an organic compound.

BPA is a white solid. It is stable at room temperature, but flammable at high temperatures and sources of ignition. BPA is soluble in organic solvents such as dichloromethane and ether, and can be hydrolyzed under acidic conditions.

BPA is mainly used as a reagent and intermediate in organic synthesis reactions. It can also be used for the preparation of pesticides and dyes.

A common method for preparing BPA is to react 5-bromo-2-pyridineamine with 1- [(2,6-dichloro-3-fluorophenyl) ethoxy] bromoethane.

It should be used in a well ventilated area and appropriate personal protective equipment such as protective gloves, goggles, and clothing should be worn. During operation and storage, contact with oxidants and acidic substances should be avoided. If accidentally inhaled or ingested, seek medical attention immediately. Please conduct specific individual and environmental safety assessments based on the actual situation.
