Quality Control

Our production of 5-Hydroxy-3(2H)-benzofuranone adheres to stringent internal quality standards to ensure batch-to-batch consistency and reliability. Each lot is characterized and tested using advanced analytical techniques including HPLC, GC, and NMR. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment, supporting your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its light-sensitive nature and propensity for oxidation, it is recommended to handle under an inert atmosphere for long-term storage and to minimize repeated exposure to air.
