Quality Control

Our 2-tert-Octylbenzene-1,4-Diol is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including assay by HPLC and identification by FT-IR, to ensure it meets precise specifications and is free from critical impurities. A Certificate of Analysis (COA) detailing purity, physical characteristics, and test results is provided with every shipment to guarantee traceability and compliance.

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 nature of being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from strong oxidizing agents.
