Description

Sodium α-Bromo-p-Toluenesulphonate CAS NO 32014-22-5 is a versatile organic sulfonate salt widely used as a key synthetic intermediate and alkylating agent in fine chemical manufacturing. Its primary value lies in its reactive bromine atom, which facilitates the introduction of the p-toluenesulfonyl (tosyl) group into target molecules, enabling the synthesis of complex compounds. This chemical is essential for research and production in the pharmaceutical, agrochemical, and specialty chemical industries, where precise molecular construction is critical.

Application

• Pharmaceutical Intermediate: A crucial building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for sulfonamide-based drugs.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and other crop protection agents that require sulfonate functionalities.
• Dye and Pigment Manufacturing: Serves as an intermediate in the creation of sulfonated dyes and colorants, enhancing solubility and color fastness.
• Polymer Modification: Employed to introduce sulfonate groups into polymer chains, modifying properties like hydrophilicity and ion-exchange capacity.
• Chemical Research & Development: A valuable reagent in organic synthesis laboratories for constructing complex molecular architectures and studying reaction mechanisms.
• Surfactant and Detergent Precursor: Acts as a starting material for synthesizing specialized anionic surfactants with specific performance characteristics.

Quality Control

Our Sodium α-Bromo-p-Toluenesulphonate is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets precise customer specifications. Certificates of Analysis (COA) documenting all critical parameters are available upon request, providing full traceability and compliance assurance for your quality systems.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
