NSC 677 - Introduction
5-phenyl-1,3,4-thiadiazol-2-amine is an organic compound with the chemical formula C11H9N3S. The following is a description of its nature, use, preparation and safety information:
Nature:
5-phenyl-1,3,4-thiadiazol-2-amine is a colorless crystalline solid, insoluble in water, but soluble in some organic solvents such as ethanol and dimethyl sulfoxide. It has a moderate melting point and low volatility.
Use:
5-phenyl-1,3,4-thiadiazol-2-amine has certain application value in the field of medicine. It is used as a pharmaceutical intermediate and can be used to synthesize some anti-tumor, antibacterial, anti-inflammatory and other drugs. In addition, it can also be used as a precursor of dyes and used in the field of dyeing.
Method:
The preparation method of 5-phenyl-1,3,4-thiadiazol-2-amine mainly includes two-step reaction. First, Aniline reacts with hypochlorous acid under acid catalysis to form an imine intermediate. The imine intermediate is then reacted with a thiol to produce 5-phenyl-l, 3,4-thiadiazol-2-amine. During the reaction, attention should be paid to the operating temperature and waste treatment to ensure safety.
Safety Information:
5-phenyl-1,3,4-thiadiazol-2-amine is relatively safe under correct use and storage conditions. However, it may be irritating and corrosive to the eyes and skin, and direct contact should be avoided. During operation, appropriate protective measures should be taken, such as wearing safety glasses, gloves and protective clothing. If accidentally inhaled or ingested, seek medical help immediately.
