Description

2,4-Difluoro-5-Methoxyaniline is a versatile fluorinated aniline derivative that serves as a critical building block in advanced organic synthesis. Its value lies in the unique reactivity imparted by the methoxy and fluorine substituents, enabling precise molecular construction. This high-purity intermediate is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries, particularly for developing active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: A key synthon for the synthesis of novel active pharmaceutical ingredients (APIs), especially in fluorinated drug candidates targeting central nervous system and anti-infective applications.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and pesticides, where the fluorine atoms enhance biological activity and environmental stability.
• Liquid Crystal & OLED Materials: Serves as a precursor for fluorinated aromatic diamines and other components in electronic display materials and organic light-emitting diodes (OLEDs).
• Polymer Chemistry: Acts as a monomer or modifier in the synthesis of high-performance polymers, such as polyimides and aramids, improving thermal and chemical resistance.
• Dye & Pigment Manufacturing: Employed in the synthesis of specialized fluorinated dyes and pigments that offer superior lightfastness and color properties.
• Chemical Research & Development: A valuable reagent for academic and industrial R&D in medicinal chemistry and material science for structure-activity relationship (SAR) studies.

Quality Control

Our 2,4-Difluoro-5-Methoxyaniline is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance protocols.

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). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept sealed under an inert atmosphere when not in use to prevent degradation.
