Quality Control

Every batch of (2R,4S,5R,6R)-4-Methoxy-6-Methyl-Oxane-2,5-Diol is manufactured under strict quality management systems. We employ advanced analytical techniques, including chiral HPLC, NMR, and mass spectrometry, to guarantee exceptional stereochemical purity and batch-to-batch consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your regulatory and R&D requirements.

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). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which may affect stability and handling properties. For long-term storage, consider the use of a desiccant.
