Quality Control

Our 4-(4-Methoxy-3-Methyl-Phenyl)-4-Oxo-Butyric Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets exacting specifications for use as a pharmaceutical intermediate. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at 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.
