Quality Control

Our Methyl 2-O,3-o-Dibenzoyl-4-o-(p-Tolylsulfonyl)-β-L-Arabinopyranoside is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and mass spectrometry, to ensure high chemical purity and structural integrity suitable for demanding synthetic applications. Certificates of Analysis (COA) with detailed chromatographic and spectroscopic data are provided to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. For long-term storage, consider using desiccants.
