5-Methoxy-4-methyl-3-pyridinamine(CAS: 77903-28-7)

5-Methoxy-4-methyl-3-pyridinamine is an organic compound with a molecular weight of approximately 152.14 g/mol. It is a white crystalline solid with a melting point around 145-147°C. The compound is slightly soluble in water and more soluble in organic solvents such as methanol and ethanol. It is an amine derivative and exhibits basic properties. Reactivity is moderate, and it is typically stable under normal conditions but should be stored in a cool, dry place away from direct sunlight.

5-Methoxy-4-methyl-3-pyridinamine is typically synthesized from 4-methyl-3-pyridinone via the methylation of the nitrogen atom followed by the introduction of the methoxy group. The synthesis involves the use of methyl iodide as a methylating agent and potassium carbonate as a base. This method provides good selectivity and yield, with the final product being purified by recrystallization.

5-Methoxy-4-methyl-3-pyridinamine is primarily used in the pharmaceutical industry for the synthesis of certain drugs. It also finds applications in the polymer industry, particularly in the development of functional polymers and coating materials. Additionally, it is used in sensor technology for its reactive properties and as a precursor in semiconductor manufacturing processes.

When handling 5-Methoxy-4-methyl-3-pyridinamine, it is crucial to use appropriate personal protective equipment (PPE), including gloves, safety goggles, and a laboratory coat. The compound should be handled in a well-ventilated area or a fume hood. Spills should be cleaned up immediately using appropriate absorbent materials, and the area should be flushed with water. It is essential to consult the Safety Data Sheet (SDS) for detailed information on proper handling and emergency procedures. Storage should be at room temperature in a tightly sealed container and away from direct sunlight and heat sources.
