Description

6,7-Bis[(Phenylsulphonyl)Oxy]Naphthalene-2-Sulphonyl Chloride is a high-purity, multi-functional sulfonyl chloride derivative used as a critical building block in advanced organic synthesis. This compound matters for its role in constructing complex molecular architectures, particularly in the development of specialty dyes, functional polymers, and active pharmaceutical ingredients (APIs). It is primarily needed by R&D chemists and process development teams in the pharmaceutical, agrochemical, and advanced materials industries seeking to introduce specific sulfonate or sulfonamide functionalities.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of novel drug candidates, particularly those requiring naphthalene-sulfonamide or sulfonate ester moieties.
• Dye and Pigment Synthesis: Used in the production of high-performance, sulfonated naphthalene-based dyes and optical brighteners.
• Polymer Chemistry: Acts as a monomer or cross-linking agent for creating specialty polymers with specific ionic or solubility properties.
• Agrochemical Research: Employed in the development of new herbicides and plant growth regulators where the sulfonyl chloride group is essential for bioactivity.
• Liquid Crystal & OLED Materials: A potential intermediate for synthesizing charge-transport or emissive materials in electronic displays.
• Chemical Biology Probes: Useful for labeling biomolecules or creating activity-based probes due to its reactive sulfonyl chloride group.

Quality Control

Our 6,7-Bis[(Phenylsulphonyl)Oxy]Naphthalene-2-Sulphonyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by IR and NMR spectroscopy, to ensure it meets the high standards required for research and process chemistry. Certificates of Analysis (COA) with batch-specific data are available upon request.

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 sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from strong bases and oxidizing agents.
