Quality Control

Our 2,3-Dimethylhydroquinone is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive quality assurance, with products typically meeting a purity specification of ≥98.0% (by HPLC). A detailed Certificate of Analysis (COA) is supplied with each shipment, documenting key parameters such as assay, identity, and impurity profiles. Our quality control protocols are designed to meet the stringent requirements of pharmaceutical and fine chemical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its property 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, strong acids, and bases.
