Quality Control

Our Pyrido[2,3-B]Pyrazine-6,8-Diamine, 2-Methyl- (9Ci) is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods. Certificates of Analysis (COA) detailing all specification results are provided with every shipment. We support compliance with cGMP and ICH guidelines for pharmaceutical intermediates upon request.

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 or storing under an inert atmosphere.
