3,6-Dichloro-4-methylpyridazine(CAS: 19064-64-3)

3,6-Dichloro-4-methylpyridazine (CAS: 19064-64-3) is a crystalline solid with a molecular weight of approximately 174.06 g/mol. It has a melting point of around 190-195°C. The compound is slightly soluble in water but soluble in common organic solvents like ethanol and acetone. It is reactive towards nucleophiles and exhibits electrophilic aromatic substitution reactivity.

3,6-Dichloro-4-methylpyridazine can be synthesized via the reaction of 4-methylpyridine with chlorine in the presence of a Lewis acid catalyst, such as aluminum chloride. The reaction is selective and provides good yield under mild conditions. The process involves electrophilic aromatic substitution and results in the introduction of chloro substituents at the 3 and 6 positions.

3,6-Dichloro-4-methylpyridazine (CAS: 19064-64-3) is used in various industries, particularly in pharmaceuticals for the synthesis of certain drugs. It is also employed in the production of pesticides, dyes, and as an intermediate in the synthesis of polymeric materials and sensors. Its application in semiconductors is less common but possible depending on the specific structural requirements.

When handling 3,6-Dichloro-4-methylpyridazine (CAS: 19064-64-3), it is important to use appropriate personal protective equipment (PPE), including gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or a fume hood to minimize exposure. Spills should be cleaned up using appropriate absorbents and disposed of according to local regulations. Always refer to the Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS) for detailed safety information.
