Quality Control

Our 1,2-Benzoquinone Dioxime is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing to ensure consistent purity and performance as a crosslinking agent. We provide detailed Certificates of Analysis (COA) that document key parameters such as assay, melting point, and moisture content, ensuring full traceability and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is easily oxidized (store under inert atmosphere) and should be kept away from strong oxidizers, acids, and bases. For long-term storage, consider an inert gas blanket (e.g., nitrogen or argon) to maintain product integrity.
