Benzotriazole (CAS No. 95-14-7) is a nitrogen-containing heterocyclic organic compound with a stable structure, featuring the chemical formula C₆H₅N₃ and a molecular weight of 119.12. It appears as white to pale yellowish-brown crystals or powder with no obvious odor. Although it will oxidize and discolor slowly in air, it can maintain good stability under normal temperature and pressure. As a chemical reagent with both scientific research value and industrial practicality, it demonstrates irreplaceable application potential in multiple fields relying on its unique molecular structure. Produced through mature processes, it can meet the purity and performance requirements of different scenarios.
With a density of 1.3±0.1 g/cm³, a stable melting point of 97-99℃, a boiling point of 204℃ (15 mmHg), and a flash point of 170℃, it possesses both polar and aromatic compound characteristics. It has good solubility in organic solvents such as methanol, acetone, and benzene, adapting to the needs of various application scenarios.
The mainstream preparation method is the o-phenylenediamine method, including atmospheric pressure and high-pressure process routes, with a maximum yield of 96.9%. The product purity can stably meet the standards, and it can be adjusted through different synthesis schemes to meet the differentiated needs of scientific research and industrial grades.
Although it has certain toxicity, its toxicological data and protection standards have been clarified. Risks can be effectively controlled through standardized operations. Meanwhile, the product has strong stability and can be stored for a long time by avoiding contact with oxidants and acids, ensuring controllable usage safety.
As a biochemical reagent, it can be used as an organic material in life science research, applied in scenarios such as heterocyclic compound-related experiments and molecular structure research, providing a reliable experimental carrier for researchers.
It is mainly used as a metal corrosion inhibitor, which can form a protective film on the metal surface to effectively slow down corrosion reactions. It is widely used in rust prevention treatment in fields such as machinery manufacturing, electronic equipment, and hardware accessories; it can also be used as a photographic antifogging agent to improve imaging quality.
As an important organic synthesis intermediate, relying on its nitrogen-containing heterocyclic structure, it can participate in various organic reactions, providing key support for the synthesis of compounds in fields such as pharmaceuticals and new chemical materials. It can also be used as an analytical reagent to assist chemical detection work.
Adopt wooden barrels lined with plastic bags or glass bottle packaging. The specification of glass bottles is 500g/bottle, with 20 bottles packed in one wooden case. The outer packaging is clearly marked with "light-proof" and "sealed" labels to ensure the packaging is intact during transportation.
Mixed loading and transportation with oxidants, acids, and food chemicals are strictly prohibited. Transportation vehicles must be equipped with corresponding fire-fighting equipment and leakage emergency treatment equipment to avoid mixed reaction or leakage risks during transportation.
During transportation, it is necessary to prevent sun exposure, rain, and high temperature, ensure stable loading to prevent container collapse and damage; the vehicle must be thoroughly cleaned after transportation to avoid residual pollution.
