Description

3-(4-Carboxyphenyl)Propionic Acid is a versatile aromatic carboxylic acid derivative that serves as a critical building block in advanced organic synthesis. Its bifunctional structure, featuring both a phenylpropionic acid and a benzoic acid moiety, makes it an invaluable intermediate for creating complex molecules with tailored properties. This compound is essential for researchers and manufacturers in the pharmaceutical and specialty chemical industries, particularly for developing active pharmaceutical ingredients (APIs), liquid crystal materials, and high-performance polymers.

Application

• Pharmaceutical Intermediate: A key starting material or intermediate in the synthesis of non-steroidal anti-inflammatory drugs (NSAIDs) and other bioactive compounds.
• Liquid Crystal Synthesis: Used as a precursor in the manufacture of monomers for liquid crystal displays (LCDs) and other advanced optical materials.
• Polymer Chemistry: Serves as a monomer or cross-linking agent for producing specialty polyesters, polyamides, and other high-performance polymers.
• Organic Synthesis Building Block: Employed in coupling reactions (e.g., Suzuki, Heck) and other transformations to introduce carboxylic acid functionality into complex molecular architectures.
• Agrochemical Research: Utilized in the development and synthesis of novel herbicides, fungicides, and plant growth regulators.
• Dye and Pigment Industry: Acts as an intermediate for synthesizing organic dyes, pigments, and optical brighteners.

Quality Control

Our 3-(4-Carboxyphenyl)Propionic Acid is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and FTIR, to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all relevant specifications. Our quality commitment supports applications requiring high-purity intermediates, from research and development to commercial-scale production.

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