Quality Control

Every batch of 3-Carbamoyl-3,4-Epoxy-4-Ethyl-5-Hydroxy-5-Methyl-γ-Butyrolactone is manufactured and tested under a strict quality management system. We provide comprehensive analytical documentation to ensure traceability and compliance with your project specifications. A detailed Certificate of Analysis (COA), including purity assay and impurity profile, is supplied with each shipment to guarantee consistency and support your regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the product must be stored in a cool, dry place, ideally at controlled room temperature (15-25°C). For long-term storage, consider using desiccants or storing under an inert atmosphere to maintain stability and purity.
