Description

4-[(2-Hydroxyethyl)Amino]Benzoic Acid is a versatile organic intermediate featuring both a carboxylic acid and a hydroxylated amino functional group. This unique bifunctional structure makes it a valuable building block for synthesizing more complex molecules, particularly in the pharmaceutical and specialty chemical sectors. Key industries that utilize this compound include pharmaceutical R&D, polymer chemistry, and the production of advanced UV absorbers and dyes.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring a benzoic acid core with solubilizing side chains.
• UV Absorber Synthesis: Serves as a critical building block for manufacturing advanced organic UV filters used in sunscreens and coatings to protect against UVA/UVB radiation.
• Polymer Modification: Used to introduce hydrophilic and reactive sites into polymer backbones, enhancing properties like dyeability, adhesion, and biocompatibility.
• Dye and Pigment Manufacturing: Acts as an intermediate in the production of azo dyes and other colorants, contributing to chromophore development.
• Crosslinking Agent: Its dual functionality allows it to act as a crosslinker in resin and epoxy formulations, improving network density and material performance.
• Bioconjugation Chemistry: Useful in biochemical research for coupling reactions, linking molecules via its carboxylic acid or amine groups.

Quality Control

Our 4-[(2-Hydroxyethyl)Amino]Benzoic Acid is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee traceability and 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 after opening to minimize exposure to atmospheric moisture. Keep away from incompatible materials such as strong oxidizing agents.
