1-nitroso-1H-benzotriazole

1-Nitroso-1H-benzotriazole, also known as NBTA-N-oxide, is a chemical compound with the molecular formula C7H5N3O2. It is a pale yellow powder that is soluble in organic solvents such as chloroform and methylene chloride. NBTA-N-oxide is primarily used as a photoinitiator in the production of polymer materials, particularly in the production of photopolymer printing plates for use in the printing industry. It is also used as an intermediate in the synthesis of organic compounds and as a stabilizer for rubber and plastic materials. The chemical structure of NBTA-N-oxide consists of a benzotriazole ring with a nitroso group attached to one of its nitrogen atoms. This nitroso group is responsible for the compound's ability to undergo photolysis, or the process of breaking down into smaller molecules upon exposure to light. This property makes NBTA-N-oxide an effective photoinitiator, as it can initiate polymerization reactions when exposed to UV light. However, it is important to note that NBTA-N-oxide is classified as a hazardous material due to its potential to cause skin irritation and respiratory distress upon exposure. As such, proper safety precautions should be taken when handling and using this compound.
