Quality Control

Our Guanosine is manufactured under a strict quality management system. Each batch is tested to ensure it meets high-purity standards suitable for pharmaceutical and research applications. Comprehensive testing includes identity confirmation, assay (HPLC), and control of related substances and residual solvents. Certificates of Analysis (COA) 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 area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption.
