1-Naphthylamine is primarily used in the production of azo dyes, which are widely employed in the textile industry for coloring fabrics. It serves as an intermediate in the synthesis of these dyes, contributing to vibrant and long-lasting colors. Additionally, it is utilized in the manufacture of certain rubber chemicals, such as antioxidants, enhancing the properties of rubber products. In the agricultural sector, it finds application in the production of pesticides, helping to protect crops from pests. It also plays a role in research and development as a reagent in various chemical reactions and analytical processes. However, due to its carcinogenic properties and health risks, its industrial use is restricted in many countries, and it is primarily employed in controlled laboratory environments.
