Description

4-(2-Bromoethyl)Benzenesulfonic Acid is a versatile organosulfur compound featuring both a bromoethyl and a sulfonic acid functional group. This bifunctional nature makes it a valuable chemical intermediate for synthesizing more complex molecules in advanced research and manufacturing. It is primarily sought after by pharmaceutical and agrochemical industries for the development of active ingredients and specialty chemicals.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring sulfonamide or aryl-ethyl-bromide motifs.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators.
• Dye and Pigment Manufacturing: Serves as a precursor for sulfonated dyes and specialty colorants.
• Polymer Modification: Acts as a functional monomer or cross-linking agent to introduce ionic or reactive sites into polymers.
• Chemical Research (R&D): Employed in organic synthesis for C-C bond formation (e.g., Suzuki coupling) and as a precursor for other benzenesulfonate derivatives.
• Surfactant and Detergent Intermediate: Potential use in creating specialized anionic surfactants.

Quality Control

Our 4-(2-Bromoethyl)Benzenesulfonic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise customer specifications and industry standards. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent degradation from atmospheric moisture.
