Chemical Properties
LIGHT BROWN TO GREY CRYSTALLINE POWDER
Uses
2-Bromo-3-hydroxypyridine is used to produce 2-bromo-4,6-diiodo-3-pyridinol. It is also used in azo dyes and in the synthesis of pterocellin A by reacting with kojic acid and in synthesis of orelline.
Synthesis
109-00-2
6602-32-0
The general procedure for the synthesis of 2-bromo-3-hydroxypyridine from 3-hydroxypyridine was as follows: (a) A hypobromite solution was prepared by slowly adding bromine (2.74 mL, 8.49 g, 5.31 mmol) to 10% sodium hydroxide solution (50 mL) at 5°C to 10°C. Subsequently, this hypobromite solution was added dropwise to 10% sodium hydroxide solution (50 mL) containing 3-hydroxypyridine (5.0 g, 52.6 mmol) over 20 minutes. The reaction mixture was continued to be stirred for 30 minutes. The pH of the reaction solution was adjusted to 6-7 with acetic acid. the mixture was cooled to 5°C and maintained for 1 h. The solid product was subsequently collected by filtration. The product was washed with water and dried under vacuum at 85°C to give 2-bromo-3-hydroxypyridine (6.22 g, 67% yield).
