1-METHYLPYRIDINIUM CHLORIDE - Introduction

1-methylpyridinium chloride is an organic compound with the chemical formula C6H7ClN. It is prepared by the reaction of 1-picoline with hydrogen chloride.

1-methylpyriridinium chloride is a colorless to pale yellow crystal, soluble in water and organic solvents. It has a strong odor and is irritating to the skin, eyes and respiratory tract.

1-methylpyriridinium chloride has certain application value. It is often used as a catalyst, intermediate and flame retardant. In the catalytic reaction, it can catalyze the addition reaction of aldehyde and ketone, catalytic oxidation reaction and so on. As an intermediate, it can be used in the synthesis of various organic compounds, such as heterocyclic compounds and drugs. In addition, it can also be used as a flame retardant in plastics and polymers to reduce the risk of fire.

Because 1-methylpyridinium chloride is irritating, you need to pay attention to safety when using it. During the operation, protective equipment such as protective glasses and gloves should be worn to avoid direct contact with the skin and inhalation of its particles. During storage and handling, avoid contact with oxidants and strong acids to avoid unsafe chemical reactions. In case of accidental exposure, immediately flush the affected area with plenty of clean water and seek prompt medical attention.
