Quality Control

Our 2,5-Diisooctylhydroquinone is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot is subjected to comprehensive analytical testing, including chromatographic purity assays and identity confirmation. Certificates of Analysis (COA) detailing all specifications are 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 place at 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 heat, sparks, and open flame.
