Description

5-Bromo-2-Chlorobenzenesulfonic Acid is a versatile halogenated benzenesulfonic acid derivative that serves as a critical building block in advanced organic synthesis. Its value lies in its dual functionality, providing both a reactive sulfonic acid group and halogen substituents for further derivatization. This compound is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries, where it is used to create novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring specific halogenated aromatic scaffolds.
• Agrochemical Synthesis: Used in the development of herbicides, fungicides, and insecticides, where the bromo and chloro groups enable targeted bioactivity.
• Dye and Pigment Manufacturing: Functions as an intermediate for creating sulfonated dyes and specialty colorants with enhanced properties.
• Ligand and Catalyst Development: Serves as a starting material for synthesizing specialized ligands used in metal catalysis and coordination chemistry.
• Polymer Modification: Employed to introduce sulfonic acid groups into polymer backbones, modifying properties like hydrophilicity and ion-exchange capacity.
• Research & Development: A valuable reagent in academic and industrial R&D for exploring new chemical entities and reaction pathways.

Quality Control

Our 5-Bromo-2-Chlorobenzenesulfonic Acid is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets the high standards required for synthetic applications. Certificates of Analysis (COA) documenting all specifications are provided and available upon request.

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 sealed to prevent absorption of atmospheric moisture. Keep away from incompatible materials such as strong bases and oxidizing agents.
