Description

3-Amino-Alpha,Alpha,α-Trifluorotoluene-4-Sulphonic Acid is a high-value, multi-functional aromatic intermediate containing both amino and sulfonic acid groups on a trifluoromethylated benzene ring. This unique structure makes it a critical building block for synthesizing advanced materials and specialty chemicals where specific solubility, acidity, and electronic properties are required. It is primarily sought after by research institutions and industrial manufacturers in the pharmaceutical, agrochemical, and dyestuff sectors for developing novel active ingredients and functional dyes.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for drugs requiring a sulfonamide or aniline moiety with enhanced lipophilicity from the trifluoromethyl group.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and pesticides, where the trifluoromethyl group often improves biological activity and environmental stability.
• Dyestuff and Pigment Manufacturing: Serves as a crucial intermediate for creating acid dyes, reactive dyes, and organic pigments, contributing to color fastness and solubility.
• Liquid Crystal & Electronic Materials: Acts as a building block for functional molecules used in liquid crystal displays (LCDs) and organic electronic materials due to its polar and electron-withdrawing characteristics.
• Corrosion Inhibitor Formulation: Utilized in specialty chemical formulations designed to protect metals, leveraging its anionic sulfonic acid group.
• Research & Development: Employed in academic and industrial R&D for exploring new chemical entities, metal-organic frameworks (MOFs), and polymer modifiers.

Quality Control

Our 3-Amino-Alpha,Alpha,α-Trifluorotoluene-4-Sulphonic Acid is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and impurity profiles. Certificates of Analysis (COA) detailing results from HPLC, NMR, and titration methods are available upon request to support your quality assurance and regulatory compliance needs.

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 sealed to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
