Quality Control

Our production of Pyrazolo[1,5-A]Pyrimidine-6-Carboxylic Acid, 7-Amino-2-Methyl-, Methyl Ester (9Ci) adheres to stringent quality protocols suitable for pharmaceutical intermediate applications. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via NMR and MS. Certificates of Analysis (COA) detailing all specifications are provided to ensure traceability and compliance with your internal quality standards and cGMP guidelines where applicable.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a 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.
