1H-tetrazole

　　Main Uses

　　Pharmaceutical Synthesis:

　　As an intermediate for cephalosporin antibiotics: In the synthesis of cephalosporins (such as cefazolin, ceftezole), 1H-tetrazole is used to construct the 7-position side chain, enhancing the antibacterial activity and stability of the drugs;

　　Antiviral drug intermediate: Its derivatives can inhibit viral replication (such as influenza viruses) and are used in antiviral drug research and development;

　　Metal chelating agent: Coordinates with metal ions (such as zinc, copper) for the preparation of metal-based drugs or diagnostic reagents.

　　Materials Field:

　　High-energy material additive: The tetrazole ring contains high nitrogen content; its derivatives (such as 5-aminotetrazole) can be used to prepare explosives and propellants, reducing smoke pollution;

　　Polymer material monomer: Introduced into polymer chains via substitution reactions, imparting properties such as antibacterial and flame retardant characteristics to the materials.

　　Organic Synthesis:

　　Protecting group: Used as a carboxyl protecting group in peptide synthesis, featuring mild reaction conditions and easy removal;

　　Ligand: Forms complexes with transition metals (such as palladium, platinum) and participates as a catalyst in coupling reactions, cyclization reactions, etc.
