Quality Control

Our 2-Hydroxy-3-Methyl-1,4-Naphthoquinone is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide Certificates of Analysis (COA) with key parameters such as assay (HPLC), melting point, and impurity profile. Specifications can be tailored to meet specific customer requirements for research or industrial use.

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 light-sensitive and easily oxidized nature, it is recommended to handle under an inert atmosphere for long-term storage and to minimize headspace in opened containers.
