How should 4-Methylcinnamic acid (CAS: 1866-39-3) be stored?

4-Methylcinnamic acid (CAS: 1866-39-3) should be stored in a cool, dry place away from direct sunlight and moisture. It should be kept in a tightly sealed container to prevent degradation. Proper storage conditions include a temperature range of 15-25°C (59-77°F) and a relative humidity less than 60%. It is important to avoid contact with oxidizing agents and to handle it with care to prevent potential fires or explosions.
