Description

6-Benzoxazolesulfonylchloride,2,3-Dihydro-3-Methyl-2-Oxo-(9Ci) is a specialized heterocyclic sulfonyl chloride derivative, serving as a critical building block in advanced organic synthesis. Its reactive sulfonyl chloride group makes it a versatile intermediate for constructing complex molecules, particularly in the development of active pharmaceutical ingredients (APIs) and functional materials. This high-purity intermediate is essential for research and production chemists in the pharmaceutical, agrochemical, and specialty chemical industries seeking to introduce the benzoxazole sulfonamide pharmacophore.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel drug candidates, particularly those targeting enzymes where sulfonamide groups are crucial for binding.
• Agrochemical Synthesis: Used in the development of new herbicides, fungicides, and insecticides that incorporate the benzoxazole scaffold for enhanced bioactivity.
• Material Science Research: Serves as a monomer or functionalization agent for creating polymers with specific optical or electronic properties.
• Chemical Biology Probes: Employed in the design and synthesis of activity-based probes (ABPs) for studying enzyme function and mechanism.
• Dye and Pigment Intermediate: Utilized in the production of specialized dyes and optical brighteners.
• Custom Synthesis & Contract Manufacturing: A vital starting material for custom synthesis projects requiring the introduction of a sulfonamide linkage onto a benzoxazole core.

Quality Control

Our 6-Benzoxazolesulfonylchloride,2,3-Dihydro-3-Methyl-2-Oxo-(9Ci) is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for pharmaceutical and advanced synthetic applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee traceability and consistency for our global B2B clients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 anhydrous conditions, preferably under an inert atmosphere such as nitrogen or argon, to prevent decomposition. Keep away from heat, open flames, and incompatible materials like strong bases and oxidizing agents.
