Quality Control

Our deuterated and specialty intermediates are produced under strict quality management systems to ensure batch-to-batch consistency and high chemical purity. Each lot undergoes comprehensive analytical characterization, including NMR (¹H, ¹³C), HPLC, and mass spectrometry, to confirm identity, isotopic enrichment (D9), and purity. A detailed Certificate of Analysis (COA) documenting all specifications is provided with every shipment to support your quality assurance and regulatory needs.

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). The container should be kept in a well-ventilated area and protected from moisture.
