Description

3-(1H-Tetrazol-1-Yl)Benzenesulfonyl Chloride is a specialized heterocyclic sulfonyl chloride derivative, serving as a critical building block in advanced organic synthesis. Its core value lies in its dual functionality, combining a reactive sulfonyl chloride group with a tetrazole moiety, enabling its use in the creation of complex molecular architectures. This high-purity intermediate is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries, particularly for developing active ingredients and novel chemical entities.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), especially for compounds targeting cardiovascular and central nervous system diseases.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and insecticides, leveraging the bioactivity of the tetrazole ring.
• Material Science: Building block for creating functional polymers and advanced materials with specific electronic or adhesive properties.
• Chemical Biology & Proteomics: Serves as a versatile reagent for bioconjugation and labeling strategies in probe development.
• Cross-Coupling Reactions: Acts as an electrophile in Suzuki, Heck, and other palladium-catalyzed cross-coupling reactions to introduce the benzenesulfonyl-tetrazole moiety.
• Ligand & Catalyst Development: Useful for synthesizing novel ligands for transition metal catalysis and organocatalysts.

Quality Control

Our 3-(1H-Tetrazol-1-Yl)Benzenesulfonyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and mass spectrometry, to ensure high chemical purity and identity confirmation. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all relevant specifications. Our quality commitment ensures material consistency and reliability for your critical research 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 (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases and oxidizing agents.
