‌‌N,N-dimethylaniline is in the form of a light yellow oily liquid. The following is a detailed description of the form of N,N-dimethylaniline:

‌Appearance‌: Light yellow to brown oily liquid with a pungent odor, and easily oxidized to darken the color.
‌Physical properties‌: Insoluble in water, but soluble in organic solvents such as ethanol, ether, and chloroform. Its boiling point is 193.5±0.0 °C, melting point is 1.5-2.5 °C, and density is about 1.0±0.1 g/cm3.
In summary, N,N-dimethylaniline appears as a light yellow oily liquid at room temperature and pressure, and has certain physical and chemical properties.

‌N,N-Dimethylaniline (DMBA) is an organic compound that is mainly used as a dye intermediate and has a variety of industrial uses. The following are the main uses of N,N-dimethylaniline:

‌Dye intermediates‌: Used to make vanillin, azo dyes, triphenylmethane dyes, etc.
‌Solvents and stabilizers‌: Due to its specific chemical properties, N,N-dimethylaniline can be used as a solvent and stabilizer.
‌Analytical reagents‌: In chemical analysis, N,N-dimethylaniline is also often used as a reagent.
‌Other uses‌: In addition to the above main uses, N,N-dimethylaniline can also be used in other industrial fields according to specific needs.
It should be noted that N,N-dimethylaniline is a toxic and potentially carcinogenic substance, so it is necessary to strictly abide by relevant regulations during use and storage to ensure personnel safety and environmental protection. At the same time, due to its explosiveness, packaging, storage and transportation also require special care.
