Description

2-Methyl-2H-Tetrazole-5-Carbonyl Chloride is a versatile and highly reactive chemical building block, primarily used as an acylating agent in organic synthesis. Its value lies in its ability to efficiently introduce the 2-methyltetrazole moiety, a key structural feature in various high-performance materials and active pharmaceutical ingredients. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries developing novel compounds with specific biological or material properties.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly those containing the tetrazole ring system, which is a common bioisostere for carboxylic acids.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and insecticides where the tetrazole group enhances biological activity and stability.
• Polymer Chemistry: Serves as a monomer or cross-linking agent for creating specialty polymers with unique thermal or chemical resistance properties.
• Ligand and Catalyst Development: Employed in the preparation of tetrazole-based ligands for coordination chemistry and catalysis.
• Energetic Materials Research: Acts as a building block in the development of novel high-energy-density materials (HEDMs) due to the nitrogen-rich tetrazole structure.
• Peptide Mimetics and Bioconjugation: Facilitates the modification of peptides and proteins, enabling the creation of stable conjugates for biochemical and diagnostic applications.

Quality Control

Our 2-Methyl-2H-Tetrazole-5-Carbonyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure high purity and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to guarantee supply reliability and traceability for your critical R&D and production processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic and reactive nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition. Keep away from strong acids and organic solvents.
