Quality Control

Our Pyrocatechol 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 specifications for industrial and technical grades. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are available for every batch upon request to support your quality and regulatory 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 hygroscopic and easily oxidized nature, it is recommended to store under an inert atmosphere for long-term preservation and to minimize contact with air and moisture.
