4-Methyl-2-pyrimidinamine(CAS: 108-52-1)

4-Methyl-2-pyrimidinamine is a white crystalline solid with a molecular weight of approximately 107.12 g/mol. It has a solubility of about 0.3 g/100 mL in water and is soluble in organic solvents like ethanol and acetone. The compound is moderately reactive towards nucleophiles and can undergo substitution reactions. It is also prone to thermal decomposition at elevated temperatures.

4-Methyl-2-pyrimidinamine can be synthesized through the condensation of 4-methylpyrimidine with formaldehyde in the presence of a strong acid catalyst. The reaction is carried out at room temperature and yields up to 85% of the product. The selectivity and yield can be improved by using appropriate reaction conditions and optimizing the catalyst type.

4-Methyl-2-pyrimidinamine is used in various industries. It is a key intermediate in the synthesis of pharmaceuticals, particularly in the production of antifungal and antiviral drugs. It is also used in the preparation of polymer additives and as a component in the development of sensors and semiconductors.

Proper personal protective equipment (PPE) should be worn when handling 4-Methyl-2-pyrimidinamine, including gloves, goggles, and a lab coat. It should be handled in a well-ventilated area or under a fume hood. Spills should be cleaned up using appropriate absorbents, and the area should be flushed with water. Safety data sheets (SDS) should be consulted for detailed handling and disposal instructions.
