Quality Control

Every batch of 4,6-Diamino-2-Methylthio-5-Pyrimidinesulfonic Acid is manufactured and tested under a strict quality management system. Our products undergo rigorous quality testing, including HPLC and NMR analysis, to ensure compliance with precise internal specifications and customer requirements. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is available for each lot upon request.

Storage

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