Description

Sodium 4-Bromophenylmethanesulfonate is an organosulfur compound widely utilized as a versatile intermediate in advanced organic synthesis. Its value lies in its role as a key building block for introducing the 4-bromophenylmethanesulfonyl moiety, which is crucial for modifying molecular properties in target compounds. This product is essential for research and development chemists, process engineers, and manufacturers operating in the pharmaceutical, agrochemical, and specialty chemical sectors who require high-purity synthetic intermediates.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring sulfonate ester or sulfone functionalities.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and insecticides, where the bromophenyl group acts as a critical pharmacophore.
• Ligand and Catalyst Development: Serves as a starting material for creating specialized ligands used in transition metal catalysis and cross-coupling reactions.
• Material Science Research: Employed in the synthesis of monomers and functional polymers, such as sulfonated polyaryletherketones, for advanced material applications.
• Chemical Biology Probes: Useful for synthesizing probes and inhibitors that target enzymes like sulfotransferases or other biological sulfonation pathways.
• Custom Synthesis and Contract Manufacturing: A fundamental reagent for custom synthesis houses and CDMOs (Contract Development and Manufacturing Organizations) serving the fine chemical industry.

Quality Control

Our Sodium 4-Bromophenylmethanesulfonate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the stringent requirements for fine chemical intermediates. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which may affect product quality.
