‌N-methyl-m-toluidine is in the form of a yellow transparent liquid‌‌.

In addition, N-methyl-m-toluidine has a boiling point of 206°C, a relative density (20) of 0.967, and is insoluble in water‌. It is often used as a dye intermediate, such as an intermediate for tinea repellent, and needs to be stored in a sealed container, in a cool and dry place, and away from oxidants‌.

The main uses of N-methyl-m-toluidine are as follows:

‌Used as a dye intermediate‌
N-methyl-m-toluidine is an important intermediate in the production of dyes, such as for the production of cationic dyes and certain specific dye intermediates‌. Specifically, it can be used to produce dyes such as cationic red X-GRL and cationic blue X-GRRL, which are mainly used for the printing and dyeing of acrylic fibers and their blended fabrics, and can also be used for the dyeing of modified acrylic fibers and polyester‌.
‌Other applications‌

In addition to the dye industry, N-methyl-m-toluidine is also widely used in organic synthesis and can be used as an intermediate for organic synthesis‌.
In the pharmaceutical field, it may be used as a synthetic intermediate for certain drugs‌. In summary, N-methyl-meta-toluidine has important applications in dyes, organic synthesis, and medicine.
