Description

4'-Chloro-5-Isobutoxy-3-Biphenylacetic Acid is a high-purity biphenyl derivative organic acid of significant interest in advanced chemical synthesis. This compound matters as a critical pharmaceutical intermediate, enabling the production of complex active pharmaceutical ingredients (APIs) with specific therapeutic profiles. It is primarily needed by research institutions and manufacturers in the pharmaceutical, agrochemical, and fine chemical industries for developing new drug candidates and specialty chemicals.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of non-steroidal anti-inflammatory drugs (NSAIDs) and other proprietary active pharmaceutical ingredients (APIs).
• Agrochemical Research: Serves as a precursor in the development of novel herbicides and plant growth regulators.
• Fine Chemical Synthesis: Used in organic synthesis laboratories for constructing complex biphenyl-based molecular architectures.
• Material Science: Potential monomer or additive in the research of specialized polymers and liquid crystals.
• Contract Manufacturing: Supplied to CDMOs (Contract Development and Manufacturing Organizations) for custom synthesis projects.

Quality Control

Our 4'-Chloro-5-Isobutoxy-3-Biphenylacetic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure compliance with exacting standards for pharmaceutical intermediates. Certificates of Analysis (COA) detailing all test results are available upon request to support your quality assurance and regulatory documentation.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from strong bases and oxidizing agents. Due to its nature as a strong acid/organic solvent, ensure containers are properly sealed and handled with appropriate chemical safety precautions.
