Quality Control

Our 2,4'-Dihydroxybiphenyl is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive quality documentation, including detailed Certificates of Analysis (COA) for each lot, which verify identity, purity, and impurity profiles. Our standard grade meets typical industry requirements for synthesis; custom purities and specifications, including pharmaceutical grades, are available upon request.

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