Description

Anilinium Toluenesulphonate is an organic salt formed from aniline and p-toluenesulfonic acid, widely recognized for its utility as a catalyst and intermediate in specialized chemical synthesis. This compound is valued for its ability to facilitate acid-catalyzed reactions under mild conditions, offering an efficient alternative to traditional strong mineral acids. It is primarily sought by the pharmaceutical, agrochemical, and specialty chemical industries for applications in research, process development, and fine chemical manufacturing where precise control over reaction pathways is critical.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and other drug precursors.
• Catalyst in Organic Synthesis: Acts as a mild and efficient acid catalyst for esterification, condensation, and protection/deprotection reactions.
• Agrochemical Production: Serves as a key building block in the manufacture of certain herbicides, fungicides, and plant growth regulators.
• Dye and Pigment Manufacturing: Employed in the synthesis of complex organic dyes and colorants.
• Polymer Chemistry: Functions as a curing agent or catalyst in the production of specific resins and polymers.
• Research & Development: A valuable reagent in academic and industrial R&D labs for exploring new synthetic methodologies.

Quality Control

Our Anilinium Toluenesulphonate is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing to ensure consistent purity, identity, and performance. We provide full traceability and Certificates of Analysis (COA) are available for all shipments, detailing key parameters such as assay, impurity profile, and physical characteristics. Our quality systems are designed to meet the rigorous demands of industrial and research applications.

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