Description

3,5-Bis(Methylsulfonyl)Aniline is a high-purity, functionalized aniline derivative characterized by its two methylsulfonyl substituents. This compound serves as a critical advanced pharmaceutical intermediate (API) and a versatile building block in organic synthesis, enabling the introduction of both aniline and sulfone functionalities. It is primarily utilized by research and development teams in the pharmaceutical, agrochemical, and specialty chemical industries for creating novel active compounds and fine chemicals.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of complex drug molecules, particularly those targeting specific enzyme inhibition or receptor modulation.
• Agrochemical Synthesis: Used in the development of new herbicides, fungicides, and insecticides, leveraging its bio-active scaffold.
• Dye and Pigment Manufacturing: Acts as a building block for creating specialized sulfone-containing dyes with enhanced properties.
• Polymer Chemistry: Serves as a monomer or cross-linking agent for producing high-performance polymers and resins.
• Material Science Research: Employed in the development of organic electronic materials and advanced functional materials.
• Organic Synthesis Reagent: Utilized in palladium-catalyzed cross-coupling reactions and other transformations to construct complex molecular architectures.

Quality Control

Our 3,5-Bis(Methylsulfonyl)Aniline is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all relevant specifications. Our quality commitment aligns with cGMP principles where applicable, supporting its use in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic and light-sensitive nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and oxidation. Keep away from heat and incompatible materials.
