It is a colorless liquid with a characteristic odor, and is highly soluble in water, ethanol, and methanol.
The production process of 5-bromopyrimidin-2-yl)acetic acid involves several steps, including the synthesis of the starting material, the reaction conditions, and the purification and isolation of the final product.

The synthesis of the starting material for the production of 5-bromopyrimidin-2-yl)acetic acid typically involves the reaction of pyridine-N-oxide with chloroacetyl chloride in the presence of a solvent such as ether or dichloromethane.
The reaction is exothermic and requires careful temperature control to avoid unwanted side reactions.

Once the starting material has been synthesized, the next step in the production process is the reaction of the starting material with bromine in the presence of a solvent such as ether or acetonitrile.
The reaction conditions, including temperature and reaction time, must be carefully controlled to ensure the desired reaction occurs.

After the reaction is complete, the reaction mixture is typically quenched with an appropriate solvent such as water or sodium bicarbonate solution.
The mixture is then extracted with an organic solvent such as ethyl acetate or dichloromethane, and the organic layer is dried with anhydrous sodium sulfate.

The organic layer is then treated with a strong acid such as hydrochloric acid, and the resulting precipitate is collected by filtration and washed with a solvent such as ethanol or methanol.
The precipitate is then dried under vacuum to remove any residual solvent.

The final step in the production process is the purification and isolation of 5-bromopyrimidin-2-yl)acetic acid.
This typically involves dissolving the precipitated product in a suitable solvent such as ethanol or methanol, and then passing the solution through a column packed with an appropriate adsorbent such as silica gel or activated carbon.
The eluted product is then collected and concentrated to obtain a pure sample of 5-bromopyrimidin-2-yl)acetic acid.

Overall, the production process of 5-bromopyrimidin-2-yl)acetic acid is a multi-step process that requires careful control of reaction conditions and purification steps to ensure the desired product is obtained in a pure form.
