Quality Control

Our production of 3-tert-Butyl-2-Hydroxy-5-Methoxybenzoic 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 precise customer specifications. A Certificate of Analysis (COA) detailing all test results is provided with each shipment and is 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 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 absorption of atmospheric moisture. For long-term storage, consider using an inert atmosphere to minimize potential oxidation.
