Description

4-Hydroxy-4-(4-Methoxy-Phenyl)-Butyric Acid is a versatile organic intermediate characterized by its hydroxyl and carboxylic acid functional groups on a butyric acid chain attached to a methoxy-substituted phenyl ring. This unique structure makes it a valuable building block for the synthesis of more complex molecules in advanced chemical manufacturing. It is primarily sought after by research institutions and industrial manufacturers in the pharmaceutical and fine chemical sectors for developing active pharmaceutical ingredients (APIs) and specialty compounds.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of various drug candidates and active pharmaceutical ingredients (APIs), particularly those targeting neurological and inflammatory pathways.
• Fine Chemical Synthesis: Serves as a crucial building block for creating complex organic molecules used in agrochemicals, dyes, and specialty polymers.
• Research & Development: Utilized in academic and industrial R&D labs for method development, process chemistry, and exploring new synthetic routes.
• Chiral Compound Production: Its structure can be leveraged in the synthesis of enantiomerically pure compounds for high-value applications.
• Liquid Crystal & Material Science: Potential use as an intermediate in the production of advanced materials and liquid crystal displays (LCDs).

Quality Control

Our 4-Hydroxy-4-(4-Methoxy-Phenyl)-Butyric Acid is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR spectroscopy, to ensure it meets precise customer specifications and industry standards. A comprehensive Certificate of Analysis (COA) detailing all test results 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 after opening to prevent degradation from atmospheric moisture.
