Description

3-Amino-4-Fluorobenzoic Acid Hydrochloride is a high-purity fluorinated aromatic amine salt, serving as a critical building block in advanced organic synthesis. Its molecular structure, featuring both an amino group and a fluorine substituent on the benzoic acid core, makes it an invaluable intermediate for creating complex molecules with tailored properties. This compound is essential for research and production in the pharmaceutical and agrochemical industries, where it is used to develop active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for fluorinated drug candidates targeting CNS disorders, anti-infectives, and oncology.
• Agrochemical Synthesis: Building block for developing novel herbicides, fungicides, and pesticides, where the fluorine atom enhances biological activity and environmental stability.
• Liquid Crystal & OLED Materials: Used in the production of fluorinated aromatic components for electronic display materials and organic light-emitting diodes (OLEDs).
• Polymer Modification: Intermediate for introducing fluorinated aniline moieties into polymer chains to alter thermal stability, chemical resistance, and surface properties.
• Dye & Pigment Manufacturing: Serves as a starting material for synthesizing specialized fluorinated dyes and pigments with unique color fastness and spectral properties.
• Bioconjugation & Probe Development: Useful in biochemical research for creating fluorescent probes and conjugation linkers due to its reactive amine and carboxylic acid groups.

Quality Control

Our 3-Amino-4-Fluorobenzoic Acid Hydrochloride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets the high-purity standards required for pharmaceutical and fine chemical applications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment. We adhere to cGMP principles where applicable to ensure supply chain reliability and batch-to-batch consistency for our global customers.

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). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect purity and stability.
