Description

4-Amino-2-Ethylbenzoic Acid is a versatile aromatic amine derivative with a benzoic acid core structure, serving as a critical building block in advanced organic synthesis. Its value lies in its bifunctional nature, providing both an aromatic amine and a carboxylic acid group for sequential or convergent chemical modifications. This compound is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries, where it is used to develop active ingredients and functional intermediates.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of non-steroidal anti-inflammatory drugs (NSAIDs), local anesthetics, and other active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators, leveraging its aromatic ring system for bioactivity.
• Dye and Pigment Manufacturing: Serves as a diazo component or coupling agent in the synthesis of azo dyes and high-performance pigments.
• Polymer Chemistry: Acts as a monomer or chain modifier in the production of specialty polyamides, polyimides, and epoxy curing agents.
• Chemical Research: Employed as a standard or reagent in methodological development and analytical chemistry studies.
• Liquid Crystal & OLED Materials: A building block for creating advanced organic electronic materials due to its planar structure and functional handles.

Quality Control

Our 4-Amino-2-Ethylbenzoic Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, IR for identification, and residual solvent analysis, to ensure it meets the high standards required for synthesis. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect stability and handling properties.
