Quality Control

Our deuterated standards are produced under strict quality management systems to ensure the highest isotopic purity and chemical integrity. Each batch is characterized using advanced analytical techniques including NMR and high-resolution mass spectrometry. A comprehensive Certificate of Analysis (COA) is provided, detailing isotopic enrichment, chemical purity, and chromatographic data to support your traceability and compliance requirements (e.g., ISO 17025, FDA guidelines).

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. Store away from strong oxidizing agents.
