Widely used as a key intermediate in organic synthesis, particularly in the preparation of benzotriazole derivatives, which are valuable in pharmaceuticals and agrochemicals. It serves as a building block for creating compounds with potential biological activities, such as antimicrobial, antiviral, and anti-inflammatory agents. Additionally, it is utilized in the development of corrosion inhibitors, especially for metals, due to the benzotriazole moiety's ability to form protective layers on surfaces. Its role in synthesizing UV stabilizers for polymers and coatings is also notable, enhancing the durability of materials exposed to sunlight.
