5-Pyrimidinecarbonitrile(CAS: 40805-79-6)

5-Pyrimidinecarbonitrile (CAS: 40805-79-6) is a crystalline solid with a molecular weight of approximately 114.07 g/mol. It is slightly soluble in water and ethanol but soluble in organic solvents like acetonitrile. Chemically, it is highly reactive, especially towards nucleophiles and electrophiles. It is insoluble in acids and bases. This compound is known for its high reactivity in nucleophilic substitution reactions.

5-Pyrimidinecarbonitrile is typically synthesized by the nitrilation of 5-formamidopyrimidine in the presence of a suitable catalyst, such as a Lewis acid like aluminum chloride. The reaction is carried out in an organic solvent like acetonitrile at elevated temperatures. The process yields a product with high purity, and the selectivity and yield can be controlled by adjusting reaction conditions such as temperature and catalyst concentration.

5-Pyrimidinecarbonitrile (CAS: 40805-79-6) has applications in the pharmaceutical industry, where it is used as a precursor for the synthesis of certain drugs. It is also utilized in the polymer industry for the development of new materials with specific properties. Additionally, it serves as a key component in the production of sensors and semiconductors, due to its unique chemical reactivity and structural properties.

When handling 5-Pyrimidinecarbonitrile (CAS: 40805-79-6), it is essential to wear appropriate personal protective equipment (PPE), including gloves, safety goggles, and a lab coat. The compound should be handled in a well-ventilated area or a fume hood due to its volatility and potential reactivity. Spills should be cleaned up immediately using appropriate materials, and the area should be thoroughly washed down. Consult the Safety Data Sheet (SDS) for detailed handling and emergency procedures.
