Quality Control

Our production of 3-(3-tert-Butyl-4-Hydroxyphenyl)Propionic Acid adheres to stringent quality management protocols. Every batch is subjected to comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting specifications for use in sensitive applications like polymer stabilization. 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 room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere for long-term preservation. Keep away from strong oxidizing agents, strong bases, and heat sources.
