The synthesis method of 3-bromo-5-fluoro-2-methoxypyridine is described in ancient books, and it often follows several paths. First, the compound containing the pyridine ring is started, and bromine and fluorine atoms are introduced by halogenation. First, appropriate pyridine derivatives are taken. Under specific reaction conditions, brominated reagents such as N-bromosuccinimide (NBS) are used in organic solvents to control factors such as temperature and reaction time, so that bromine atoms precisely replace hydrogen atoms at specific positions of the pyridine ring to obtain bromine-containing pyridine intermediates. Then, using fluorinated reagents such as potassium fluoride (KF), with the help of a phase transfer catalyst, through a nucleophilic substitution reaction, the fluorine atom is connected, and then a pyridine compound containing bromine and fluorine is obtained. Then through the methoxylation step, with reagents such as sodium methoxide (CH 🥰 ONa), in a suitable solvent, the methoxy group is substituted for the corresponding position of the group, and the final target product is 3-bromo-5-fluoro-2-methoxy pyridine.
Second, it is a strategy for constructing a pyridine ring. The pyridine ring structure can be established first through a series of reactions such as condensation and cyclization from nitrogen-containing and carbon-containing raw materials. For example, using β-ketone esters, ammonia sources, and halogenated hydrocarbons as starting materials, a pyridine ring is constructed through a multi-step reaction. At the same time, during the reaction process, bromine, fluorine, and methoxy are introduced in sequence under different reaction conditions and reagents. Each step of the reaction needs to be carefully regulated to ensure that the reaction proceeds in the desired direction, so as to achieve the purpose of efficient synthesis of 3-bromo-5-fluoro-2-methoxy pyridine.

I don't know what the market price of 3 - Bromo - 5 - Fluoro - 2 - Methoxypyridine is. This compound may be useful in chemical, pharmaceutical and other fields. However, its price is not constant and often varies due to many reasons.
First, the price of raw materials has a great impact. If the starting material required for the preparation of this compound is expensive, or due to the scarcity of raw materials and the difficulty of preparation, the cost will increase, and the price will also increase.
