Quality Control

Our Picrasin-D is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (IR, NMR, MS), to ensure it meets the stringent requirements for research and development. Certificates of Analysis (COA) with detailed chromatographic data are provided to guarantee traceability, consistency, and compliance with your specifications.

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 product is light-sensitive (store away from light). For long-term storage, consider storing under inert atmosphere at lower temperatures (e.g., -20°C).
