General Description

This product has been enhanced for energy efficiency.

Synthesis

121-91-5

23351-91-9

Isophthalic acid (10 g, 60 mmol) and concentrated sulfuric acid (60 mL, 98%) were added to a 100 mL round-bottomed flask and stirred until completely dissolved. N-bromosuccinimide (12.8 g, 72 mmol) was added in batches in an oil bath at 60 °C, and the addition time was kept within 10 min. The reaction mixture was stirred at 60 °C overnight. Upon completion of the reaction, it was cooled to room temperature and the reaction was quenched by addition of water/ice mixture. The precipitate was collected by filtration and washed with hexane (2 x 60 mL). The solid was dried in an oven under reduced pressure. The crude product was purified by recrystallization from ethyl acetate to give 5-bromoisophthalic acid (3 g, 20% yield) as a white solid.
