2-Aminonicotinic acid Use and Manufacturing
Add 30 ml of 5 mol·L-1 sodium hydroxide solution to a 100 ml flask, add 0.02 mol of bromine at 5 ° C, stir for 0.5 h, add 0.02 mol of 2-amide pyridine-3-carboxylic acid, and heat up to Reaction at 85 ° C for 2 h;Step 5: After completion of the reaction, a portion of the solvent was concentrated under reduced pressure, cooled, and adjusted to pH=7 with hydrochloric acid, filtered, filtered, dried and evaporated to give crystals of 2-aminopyridine-3-carboxylic acid as white solid.
A component of hair dyes.
