Products Description of 4-Nitrotoluene CAS#99-99-0
4-Nitrotoluene (CAS#99-99-0) is usually a colorless to pale yellow crystalline solid at room temperature. Its physical form is needle-like or plate-like crystals, with a relatively regular crystal structure. This substance is stable at room temperature, with a melting point of approximately 51.5℃ and a boiling point of 238.5℃. When exposed to air, it may turn slightly yellow due to trace oxidation or impurities. Its overall appearance presents typical characteristics of organic nitro compounds.
