Quality Control

Every batch of 1H-1,2,3-Triazolo[4,5-D]Pyrimidin-5-Amine is manufactured under a strict quality management system and undergoes comprehensive analytical testing to ensure identity, purity, and consistency. Our products are suitable for research and development applications, with specifications tailored to meet project-specific requirements. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are provided with each shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. For long-term storage, consider using desiccants.
