Quality Control

Our 3,5-Di-tert-Butylsalicylaldehyde is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and spectroscopic methods (IR, NMR) for identity confirmation, to ensure it meets stringent specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance with your quality requirements.

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). Keep away from strong oxidizing agents and incompatible materials. Due to its light-sensitive nature, containers should be kept in the original packaging or opaque containers until use.
