Description

2,2-Dimethylpropyl 4-Fluorobenzenesulfonate is a specialized organosulfur compound that serves as a valuable building block in advanced organic synthesis. Its core value lies in its role as a versatile sulfonate ester, enabling the introduction of the 2,2-dimethylpropyl (neopentyl) group and the 4-fluorobenzenesulfonyl moiety into target molecules. This compound is primarily needed by research and development chemists and process scale-up teams within the pharmaceutical and agrochemical industries for the synthesis of novel active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring sulfonamide or sulfonate ester functionalities.
• Agrochemical Synthesis: Used in the research and production of advanced herbicides, fungicides, and insecticides where the fluorinated aromatic group confers specific biological activity.
• Material Science Research: Acts as a monomer or cross-linking agent in the development of specialty polymers with tailored surface properties or chemical resistance.
• Ligand and Catalyst Development: Employed in organic and organometallic chemistry to create novel ligands or catalyst precursors for asymmetric synthesis.
• Chemical Biology Probes: Useful for labeling or modifying biomolecules in proteomics and diagnostic assay development due to its reactive sulfonate ester group.

Quality Control

Our 2,2-Dimethylpropyl 4-Fluorobenzenesulfonate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR spectroscopy, to ensure it meets the high standards required for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

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). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, the container should be amber-colored or stored in a dark place.
