     p-Anisidine is used mostly for producing dyes, and some smaller quantities are employed in making pharmaceuticals and liquid crystals.

     p-Anisidine is used as a reagent to indicate the secondary stage of the oxidation, it is one of the three possible isomers of the Anisidine or methoxyaniline. The other two isomers are o-Anisidine (2-methoxyaniline) and m-Anisidine (3-methoxyaniline).
The p-anisidine is widely used as an intermediate in the production of numerous azo and triphenylmethane dyes, and pigments. It is also used in the production of pharmaceuticals including the guaiacol expectorant, as an antioxidant for polymercaptan resins, and as a corrosion inhibitor for steel. Apart from the beneficial use of p-anisidine, it is toxic for human beings. The acute exposure may cause skin irritation, whereas the chronic exposure may cause headaches, vertigo, and blood complications like sulfhemoglobin, and methemoglobin. The oral exposure to anisidine hydrochloride resulted in cancer of the urinary bladder in male and female rats.
