Quality Control

Our Diosmetin-D3 is manufactured under strict quality control protocols to ensure the highest isotopic purity and chemical stability required for analytical standards. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing isotopic enrichment (D%), chemical purity (by HPLC), and spectroscopic confirmation. We adhere to industry best practices for the production of labeled compounds, ensuring reliability for your most sensitive assays.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below for long-term stability. Allow the vial to equilibrate to room temperature in a desiccator before opening to prevent moisture condensation. For short-term use, store at 2-8°C.
