Quality Control

Our Py-Ds-Dmbut-Osu is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for purity assessment and spectroscopic methods for structural confirmation. Certificates of Analysis (COA) detailing all quality parameters are available upon request to support your regulatory and R&D documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C (refrigerated) or as indicated on the label. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under anhydrous conditions, preferably with desiccant, to maintain product integrity. Allow the sealed vial to equilibrate to room temperature before opening to prevent moisture condensation.
