Quality Control

Our Ethanethiol-Sd is produced and handled under stringent quality protocols to ensure high isotopic purity and chemical integrity, meeting the exacting requirements of analytical research. Each batch is characterized by advanced spectroscopic methods, including NMR and MS, to confirm isotopic enrichment and chemical purity. A comprehensive Certificate of Analysis (COA) detailing isotopic purity (e.g., D atom %), chemical purity, and analytical data is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and easily oxidized nature, this material should be stored under an inert atmosphere (e.g., nitrogen or argon) in a cool, well-ventilated area. Recommended long-term storage temperature is 2-8°C. Handle and open containers with appropriate care in a fume hood to minimize exposure and loss.
