Products Description
4-Nitrotoluene (CAS# 99-99-0) typically exists as a colorless to pale yellow crystalline solid at room temperature. It appears in the form of needle-shaped or plate-shaped crystals with a relatively regular crystalline structure. This compound is stable at room temperature, with a melting point of approximately 51.5 °C and a boiling point of about 238.5 °C. Upon exposure to air, it may take on a slight yellow tint, often resulting from trace oxidation or the presence of impurities. Overall, its appearance exhibits the typical characteristics of organic nitro compounds.
