Quality Control

Our o-α-Glucopyranosyl-(1-4)-o-α-Xylopyranosyl-(1-4)-o-α-Xylopyranosyl-(1-4)-Glucopyranose is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR for structural confirmation, and specific optical rotation measurement, to ensure identity, strength, quality, and purity. Certificates of Analysis (COA) with detailed chromatographic data are provided and can be tailored to meet specific pharmacopeial (USP/EP) or internal quality standards upon request.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store under dry, inert conditions (e.g., in a desiccator) at a controlled room temperature of 15-25°C. For long-term storage, consider freezing at -20°C.
