Description

4-Formylphenoxy-Butyric Acid is a versatile aromatic carboxylic acid derivative featuring both a formyl and a phenoxybutyric acid functional group. This bifunctional structure makes it a valuable high-purity intermediate for the synthesis of more complex molecules in advanced research and manufacturing. It is primarily sought by pharmaceutical, agrochemical, and specialty chemical industries for applications in drug discovery, polymer modification, and ligand synthesis.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs), particularly in the development of novel therapeutic agents.
• Agrochemical Synthesis: Used in the research and production of advanced herbicides, fungicides, and plant growth regulators.
• Ligand and Chelating Agent Precursor: Serves as a starting material for creating specialized ligands used in catalysis and metal complexation.
• Polymer Modification: Employed to introduce functional groups into polymer chains, enhancing properties like adhesion, solubility, or reactivity.
• Organic Synthesis & Research: A crucial reagent in academic and industrial R&D labs for constructing complex organic frameworks and fine chemicals.
• Cross-linking Agent: Potential use in the formulation of coatings, resins, and adhesives where its reactive groups can form stable bonds.

Quality Control

We maintain a rigorous quality management system to ensure batch-to-batch consistency and high purity. Our products undergo comprehensive testing, including advanced chromatographic and spectroscopic methods, to meet exacting customer specifications. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment and is available upon request.

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 to prevent absorption of atmospheric moisture. For long-term storage, consider using an inert atmosphere to minimize potential oxidation.
