Quality Control

Our Ochratoxin B-D5 is manufactured under strict quality-controlled conditions to ensure the highest isotopic purity and chemical integrity. Each batch is characterized by advanced spectroscopic and chromatographic techniques, including NMR and HPLC-MS, to confirm deuteration level and chemical purity. A comprehensive Certificate of Analysis (COA) detailing isotopic enrichment, purity, and solvent content is provided with every shipment to support your regulatory and research requirements.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below. Allow the container to reach room temperature before opening to minimize moisture condensation. For long-term storage, keep desiccated under an inert atmosphere.
