Quality Control

Our production of 3-(4-Hydroxy-3,5-Ditert-Butyl-Phenyl)Propanoic Acid adheres to stringent quality management protocols to ensure batch-to-batch consistency and high purity. Quality is verified through comprehensive analytical testing, including HPLC, GC, and NMR. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory needs.

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 sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from strong oxidizing agents.
