Quality Control

Our 2,8-Dihydroxy-6-Methyl-9-Oxo-9H-Xanthene-1-Carboxylic Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, IR and NMR for structural confirmation, and loss on drying to control moisture content. We provide full traceability and Certificates of Analysis (COA) are available for all shipments, ensuring compliance with your research and production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed after each use to prevent degradation due to moisture absorption.
