Description

Pentafluorophenyl 2,4-Dichloro-Benzenesulfonate is a high-purity, specialized sulfonate ester derivative. This compound serves as a critical building block and reagent in advanced organic synthesis, particularly for introducing the pentafluorophenylsulfonyl (Pfp) group. It is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and materials science sectors who require precise and reliable intermediates for developing new active ingredients and functional polymers.

Application

• Pharmaceutical Intermediate: Key reagent in the synthesis of active pharmaceutical ingredients (APIs), especially for sulfonamide-based drugs.
• Agrochemical Synthesis: Used in creating novel herbicides, fungicides, and insecticides that require the pentafluorophenyl moiety for enhanced activity and stability.
• Polymer Chemistry: Acts as a monomer or cross-linking agent in the production of specialty polymers with unique thermal and chemical resistance properties.
• Ligand and Catalyst Development: Employed in organometallic chemistry to synthesize novel ligands and catalysts for asymmetric synthesis.
• Proteomics Research: Can be utilized as a derivatization agent or affinity tag in biochemical research and mass spectrometry.
• Material Science: Used in surface modification and the creation of advanced coatings and electronic materials.

Quality Control

Our Pentafluorophenyl 2,4-Dichloro-Benzenesulfonate is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and GC-MS, to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all specified parameters to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 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 degradation.
