Description

4-(n-Phthalimidyl)Benzolsulfonyl Chlorid is a high-purity, reactive sulfonyl chloride derivative used as a key synthetic intermediate. This compound matters for its role in constructing complex molecules, particularly in the development of pharmaceuticals and advanced materials. It is primarily needed by research chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries for creating novel sulfonamide-based compounds.

Application

• Pharmaceutical Intermediate: A critical building block for the synthesis of novel drug candidates, particularly those containing sulfonamide pharmacophores with potential biological activity.
• Agrochemical Research: Used in the development of new herbicides, fungicides, and insecticides where the sulfonyl group is integral to the molecule's mode of action.
• Material Science: Serves as a monomer or cross-linking agent in the synthesis of specialized polymers, resins, and advanced functional materials.
• Organic Synthesis: A versatile reagent for introducing the phthalimidyl-protected aniline sulfonyl moiety into target molecules under controlled conditions.
• Proteomics & Biochemistry: Potential use as a labeling or modifying agent for proteins and peptides due to its reactive sulfonyl chloride group.

Quality Control

Our 4-(n-Phthalimidyl)Benzolsulfonyl Chlorid is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity suitable for research and development. Each lot is analyzed using advanced chromatographic and spectroscopic techniques. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance 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). 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.
