Quality Control

Every batch of (R)-(-)-Metalaxyl-D6 (2,6-Dimethyl-D6) is produced and analyzed under strict quality management protocols. We guarantee high chemical and isotopic purity, supported by comprehensive analytical data including NMR, MS, and HPLC. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming identity, purity, and deuterium enrichment. Our quality system supports compliance with relevant standards for reference materials.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C. Due to its hygroscopic (moisture-sensitive) nature, the container should be sealed under an inert atmosphere after opening and allowed to reach room temperature before use to minimize moisture uptake.
