Quality Control

Every batch of this specialty oligosaccharide is produced and analyzed under stringent quality protocols to ensure identity, purity, and batch-to-batch consistency. Our quality system employs advanced analytical techniques including HPLC, MS, and NMR for comprehensive characterization. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting critical parameters such as assay purity, identity confirmation, and impurity profiles to support your regulatory and research requirements.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dedicated freezer. This product is hygroscopic (moisture-sensitive); allow the sealed vial to equilibrate to room temperature before opening to prevent condensation and moisture uptake. For long-term storage, consider desiccant or under an inert atmosphere.
