Quality Control

Our 4-Chloro-1-(3,5-Di-o-Toluoyl-β-D-2-Deoxyribofuranosyl)Pyrazolo[3,4-D]Pyrimidine is manufactured under strict quality control protocols to ensure high purity and batch-to-batch consistency suitable for research and pharmaceutical applications. All products undergo rigorous analytical testing, including HPLC, NMR, and mass spectrometry. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with each shipment to support your regulatory and R&D documentation needs.

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 compound is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed in a desiccated environment and away from direct light exposure to maintain stability and purity.
