Description

α-(p-Aminophenyl)Butyric Acid is a versatile aromatic amino acid derivative that serves as a critical building block in advanced organic synthesis. Its bifunctional structure, featuring both an aromatic amine and a carboxylic acid group, makes it a valuable intermediate for creating complex molecules with tailored properties. This compound is essential for research and production in the pharmaceutical and agrochemical sectors, where it is used to develop active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: Key starting material for the synthesis of active pharmaceutical ingredients (APIs), particularly in the development of non-steroidal anti-inflammatory drugs (NSAIDs) and other therapeutic agents.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and plant growth regulators, leveraging its aromatic amine functionality.
• Peptide Mimetics & Conjugation: Serves as a spacer or linker in the design of peptide analogs and for bioconjugation applications in drug delivery systems.
• Dye & Pigment Manufacturing: Acts as a precursor for azo dyes and other high-performance colorants due to its diazotizable amino group.
• Polymer Chemistry: Employed as a monomer or chain modifier in the synthesis of specialty polyamides and polyimides for high-temperature applications.
• Research & Development: A valuable reagent in academic and industrial R&D for exploring new chemical entities and reaction pathways in medicinal chemistry.

Quality Control

Our α-(p-Aminophenyl)Butyric Acid is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for pharmaceutical and fine chemical synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, identity, 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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which could affect product stability and performance.
