Description

4-Bromo-3-[(dimethylamino)sulfonyl]benzoic acid is a specialized organic building block featuring both a bromo substituent and a dimethylaminosulfonyl group on a benzoic acid core. This unique molecular architecture makes it a valuable intermediate for synthesizing complex molecules, particularly in pharmaceutical research and advanced material science. It is primarily sought by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries for constructing novel active compounds and functional materials.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel drug candidates, particularly those targeting enzyme inhibition or requiring specific sulfonamide pharmacophores.
• Agrochemical Research: Used in the development of new herbicides, fungicides, or plant growth regulators where the bromo and sulfonamide groups offer sites for further functionalization.
• Material Science Precursor: Serves as a monomer or functionalizing agent in the creation of advanced polymers, liquid crystals, or organic electronic materials.
• Chemical Biology Probe Synthesis: Utilized to create molecular probes and tags for studying biological processes and protein interactions.
• Custom Synthesis & Contract Manufacturing: A critical starting material for custom synthesis houses and CDMOs (Contract Development and Manufacturing Organizations) producing client-specific compounds.
• Academic & Institutional Research: Employed in university and government laboratories for fundamental research in organic synthesis methodology and new reaction development.

Quality Control

Every batch of 4-Bromo-3-[(dimethylamino)sulfonyl]benzoic acid is produced and tested under a strict quality management system. We employ advanced analytical techniques including HPLC, GC, NMR, and mass spectrometry to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing batch-specific results is provided with each shipment, ensuring full traceability and compliance with your research or production requirements.

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 after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
