2-Hydroxy-6-methylpyridine-3-carboxylic acid - Introduction
Acid is an organic compound with the chemical formula C≡H≡N0. Its nature is as follows:
1. Appearance: acid is white to light yellow solid.
2. Solubility: It is soluble in water and has a certain solubility.
3. Purpose: acid is an important organic synthetic intermediate used in the synthesis of other compounds. It also has certain applications in the field of medicine, for the synthesis of certain drugs and antibiotics.
4. Preparation method: A common preparation method is prepared by reacting 2-hydroxy-6-methylpyridine with an acidic reagent. For example, 2-hydroxy-6-methylpyridine can be reacted with acetic anhydride to give 2-hydroxy-6-methylpyridine-3-acetic anhydride, which is then hydrolyzed to give the pyridine.
5. Safety information: acid is generally stable and safe under normal use conditions, but it still needs to be operated in accordance with chemical standards. It may cause irritation to the eyes, skin and respiratory system, so wear appropriate protective measures during operation, such as protective glasses, gloves and a suitable face mask. When stored, it should be kept in a dry, cool place, and away from fire and oxidizing agents. If swallowed or in contact with skin, rinse immediately with water and seek medical help.
