Description

[3-(4-Fluorophenoxy)Phenyl]Sulfonyl Chloride is a high-purity, reactive sulfonyl chloride derivative, a critical building block in advanced organic synthesis. Its core value lies in enabling the precise introduction of the sulfonamide functional group, which is fundamental for modulating the biological activity and physicochemical properties of target molecules. This intermediate is essential for research and development chemists in the pharmaceutical and agrochemical industries, particularly those focused on creating novel active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: A key precursor for the synthesis of sulfonamide-based drug candidates, including potential enzyme inhibitors and receptor modulators.
• Agrochemical Synthesis: Used in the development of new herbicides, fungicides, and pesticides where the sulfonamide moiety contributes to efficacy and selectivity.
• Material Science Research: Serves as a monomer or cross-linking agent in the creation of specialized polymers with tailored properties.
• Chemical Biology Probes: Employed in the design and synthesis of activity-based probes and labeling reagents for proteomics and diagnostic research.
• Custom Synthesis & Contract Manufacturing: A vital starting material for custom synthesis houses and CDMOs (Contract Development and Manufacturing Organizations) producing high-value specialty chemicals.

Quality Control

Every batch of [3-(4-Fluorophenoxy)Phenyl]Sulfonyl Chloride is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure the compound meets the high-purity standards required for sensitive synthetic applications. A detailed Certificate of Analysis (COA) specifying identity, purity, and impurity profiles is supplied with each shipment to guarantee batch-to-batch consistency and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Recommended storage temperature: 2-8°C for long-term stability.
