Quality Control

Our 4,6-Pyrimidinediamine,2-Methoxy-(9Ci) is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. We employ advanced analytical techniques, including HPLC, GC, and NMR, to verify identity and quantify impurities. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect stability and performance. Keep away from incompatible materials.
