Quality Control

Our Benzyl 3,4-o-Isopropylidene-6-Tosyl-β-D-Galactopyranoside is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR for structural confirmation, and chiral analysis to ensure stereochemical integrity. We provide Certificates of Analysis (COA) with detailed specifications, and can support development projects with custom purity grades, including materials suitable for GMP applications.

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 nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption, which can affect stability and performance. For long-term storage, consider using desiccants.
