What is Benzotriazole Used for
For Metal Protection: BTA acts as a highly effective corrosion inhibitor,
forming a protective film to prevent rust on copper, silver, zinc, and other
metals in products like antifreeze, lubricants, and cooling water systems.

In Photographic Industry: It serves as an anti-fogging agent and stabilizer in
photographic developers and paper emulsions.

In Materials Science: 1,2,3-Benzotriazole functions as a UV absorber (light
stabilizer) in plastics (e.g., PVC) and coatings to prevent photo-aging.

In Organic Synthesis: It is used as a key intermediate, and its derivatives
(e.g., HOBt) are crucial for activating carboxyl groups during peptide
synthesis.

In Analytical Chemistry: 1,2,3-Benzotriazole(BTA) acts as an analytical reagent
for the complexometric titration of metals like silver and copper.

For Other Uses: It also serves as an anti-tarnish agent for metal surfaces and
a plant growth regulator.
