Description

(3-Methyloxetan-3-Yl)Methanesulfonyl Chloride is a specialized sulfonyl chloride derivative featuring a strained oxetane ring, making it a valuable building block for advanced organic synthesis. This compound matters for its role as a key electrophilic reagent in introducing the sulfonyl moiety and the unique 3-methyloxetan-3-yl group into target molecules. It is primarily needed by researchers and process chemists in the pharmaceutical and agrochemical industries for the development of novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: A critical reagent for the synthesis of sulfonamide-based drug candidates, particularly in medicinal chemistry programs targeting enzyme inhibition.
• Agrochemical Synthesis: Used in constructing novel sulfonyl-containing herbicides, fungicides, and plant growth regulators.
• Polymer Chemistry: Serves as a functional monomer or cross-linking agent for introducing polar, reactive sites into polymer backbones.
• Material Science: Employed in the surface modification of materials and the creation of advanced functional coatings.
• Chemical Biology: Acts as a labeling or bioconjugation reagent for probing protein function or modifying biomolecules.
• Custom Synthesis & Contract Manufacturing: A key starting material for custom synthesis houses and CDMOs (Contract Development and Manufacturing Organizations) producing complex, high-value molecules for clients.

Quality Control

Our (3-Methyloxetan-3-Yl)Methanesulfonyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and GC analysis, to ensure high chemical purity and identity confirmation. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all relevant specifications. Our production adheres to cGMP guidelines where applicable, ensuring consistency and reliability for critical R&D and scale-up 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 (typically 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 decomposition. Keep away from strong acids, bases, and oxidizing agents.
