‌M-nitrotoluene is in the form of yellow liquid or crystals, and is sometimes described as a light yellow oily liquid with the smell of nitrobenzene. This description may vary depending on the purity, storage conditions or viewing angle of m-nitrotoluene, but in general, it exists in liquid or crystalline form at room temperature.

‌M-nitrotoluene is mainly used in the preparation of m-toluidine, dyes, pesticides, color developers, plastics and synthetic fiber additives, etc.

Specifically, m-nitrotoluene, also known as 3-nitrotoluene, is an organic compound with the chemical formula C7H7NO2. It is almost insoluble in water, but soluble in ethanol, ether, chloroform and benzene, and can evaporate with water vapor. Due to its specific chemical properties, m-nitrotoluene has a wide range of applications in many fields:

In the dye industry, m-nitrotoluene is an important intermediate for the preparation of certain dyes.
In the field of pesticides, m-nitrotoluene is also used to synthesize certain pesticide products.
In addition, m-nitrotoluene is also used in the production of color developers, plastics and synthetic fiber additives, etc.
One of the most important applications is the preparation of m-toluidine, which is a major downstream product of m-nitrotoluene.

In summary, m-nitrotoluene has a wide range of applications in dyes, pesticides, color developers, plastics, synthetic fiber additives, and the preparation of m-toluidine due to its unique chemical properties.
