Quality Control

Our 2-sec-Butyl-p-Cresol is produced under a stringent quality management system to ensure batch-to-batch consistency and high purity. Each lot is analyzed against rigorous internal specifications, which typically include identity confirmation, assay, and impurity profile checks. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is easily oxidized and should be kept under an inert atmosphere (e.g., nitrogen) for long-term storage to maintain optimal quality. Keep away from strong oxidizing agents.
