Quality Control

Our production of (2-Hydroxyphenyl)Bis(4-Hydroxy-2,3,5-Trimethylphenyl)Methane adheres to a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and impurity profiling, IR for structural confirmation, and loss on drying. A Certificate of Analysis (COA) detailing all test results is provided with every shipment. We support compliance with REACH and other global regulatory frameworks as required.

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 sensitivity to oxidation, prolonged storage under an inert atmosphere (e.g., nitrogen or argon) is recommended for optimal long-term stability. Keep away from strong oxidizing agents.
