Quality Control

Every batch of 3,5-Cyclohexadiene-1,2-Dione, 4-Hydroxy-5-Methoxy-3-(1-Methyl-2-Oxopropyl)-, (-)- (9Ci) undergoes rigorous analytical testing to ensure identity, purity, and consistency. Our quality assurance protocols are designed to meet the stringent requirements of research and development applications. A comprehensive Certificate of Analysis (COA) detailing purity (typically by HPLC), chiral purity, and other critical parameters is provided with each shipment to support your quality documentation.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to the presence of quinone and ketone functional groups, this material should be kept under an inert atmosphere if long-term storage is required and stored separately from strong reducing agents.
