Description

1-Methyl-1H-Tetrazole-5-Carbonyl Chloride is a versatile and highly reactive chemical building block, primarily used as a key intermediate in the synthesis of more complex molecules. Its value lies in its ability to efficiently introduce the 1-methyltetrazole moiety, a privileged heterocyclic structure, into target compounds. This product is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries, particularly for the development of active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: A critical building block for the synthesis of active pharmaceutical ingredients (APIs), especially those containing tetrazole bioisosteres.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and insecticides where the tetrazole ring enhances biological activity.
• Peptide Chemistry: Serves as a coupling reagent or protecting group derivative in the synthesis of modified peptides and peptidomimetics.
• Material Science Research: Employed in the development of novel polymers, ligands, and metal-organic frameworks (MOFs) with specific functional properties.
• Chemical Biology Probes: Useful for creating labeled compounds and probes for studying biological systems and enzyme activity.
• Custom Synthesis & Contract Manufacturing: A key starting material for custom synthesis projects and scale-up processes in fine chemical production.

Quality Control

Our 1-Methyl-1H-Tetrazole-5-Carbonyl Chloride is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to guarantee compliance with your research and production requirements.

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). This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) to prevent decomposition. Keep away from strong acids and incompatible organic solvents.
