6-Chloro-3-pyridazinecarbonitrile(CAS: 35857-89-7)

6-Chloro-3-pyridazinecarbonitrile is a white crystalline solid with a molecular weight of approximately 165.01 g/mol. It has a low solubility in water but is more soluble in organic solvents like acetone and ethanol. Chemically, it is relatively stable under normal conditions but can undergo hydrolysis in the presence of moisture or acid. It is a potent electrophile and can react with nucleophiles to form various adducts.

6-Chloro-3-pyridazinecarbonitrile is usually synthesized via the reaction of chloroacetonitrile with 3-pyridazinecarboxaldehyde. The reaction is typically catalyzed by a strong acid like concentrated sulfuric acid. The yield is around 85-90%, with good selectivity for the desired product. The reaction is exothermic and must be carefully monitored to prevent side reactions.

6-Chloro-3-pyridazinecarbonitrile finds application in the pharmaceutical industry, where it is used as an intermediate in the synthesis of certain drugs. It is also utilized in the polymer industry for the development of advanced polymers with specific properties. Additionally, it is employed in the electronics industry for the production of semiconductors and sensors due to its unique electronic properties.

When handling 6-Chloro-3-pyridazinecarbonitrile, it is crucial to wear appropriate personal protective equipment, including gloves, goggles, and a lab coat. This compound should be handled in a well-ventilated area or a fume hood due to its potential to release toxic fumes. Spills should be cleaned up immediately with appropriate containment measures. Always consult the Safety Data Sheet (SDS) for detailed handling and storage instructions.
