Quality Control

Every batch of our deuterated steroid compounds is produced and analyzed under strict quality management systems. We guarantee high chemical and isotopic purity through advanced analytical techniques including NMR, HPLC, and high-resolution mass spectrometry. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing purity, isotopic enrichment, and solvent content. Our production adheres to standards suitable for research and diagnostic use.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to prevent degradation from atmospheric moisture. For long-term storage, consider storing under an inert atmosphere.
