Quality Control

Our Methyl 4,6-o-Benzylidene-D-Altropyranoside is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, optical rotation measurement, and spectroscopic identification (NMR, IR), to ensure it meets the high standards required for research and synthesis. Certificates of Analysis (COA) with detailed chromatograms and spectral 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 place at a controlled room temperature (typically 15-25°C). This compound may be hygroscopic (moisture-sensitive); therefore, the container should be kept tightly sealed in a dry environment. For long-term storage, consider using desiccant.
