Description

2,4-Dichloro-3-Formylbenzenesulfonic Acid is a versatile and highly functionalized aromatic sulfonic acid derivative, serving as a critical building block in advanced organic synthesis. Its unique structure, featuring both a formyl group and a sulfonic acid moiety on a dichlorinated benzene ring, makes it an invaluable intermediate for creating complex molecules with tailored properties. This compound is essential for research and development chemists and process engineers in the pharmaceutical, agrochemical, and specialty chemical industries who require high-purity, reactive intermediates for constructing active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for drugs targeting specific receptors or enzymes.
• Agrochemical Synthesis: Used in the manufacture of advanced herbicides, fungicides, and plant growth regulators, leveraging its reactive sites for structural diversification.
• Dye and Pigment Manufacturing: Serves as a foundational component for producing sulfonated azo dyes and other complex colorants with enhanced solubility and fastness properties.
• Ligand and Catalyst Development: Employed in research to create novel sulfonated ligands for metal catalysis and asymmetric synthesis.
• Polymer Modification: Acts as a functional monomer or cross-linking agent to introduce ionic character or reactive handles into polymer backbones for specialty resins and ion-exchange materials.
• Chemical Research & Development: A valuable reagent for exploring new organic reactions and constructing molecular libraries for high-throughput screening in drug discovery.

Quality Control

Every batch of 2,4-Dichloro-3-Formylbenzenesulfonic Acid is manufactured and tested under a strict quality management system. We employ advanced analytical techniques, including HPLC, NMR, and titration, to ensure identity, purity, and consistency meet the high standards required for synthetic applications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and compliance with your specifications.

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 and strong acid properties, the container must be kept tightly sealed and separated from bases and reactive materials.
