Quality Control

Our Viroxime is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the stringent requirements for pharmaceutical intermediates. Certificates of Analysis (COA) are provided with every shipment, detailing all specified parameters. We adhere to cGMP guidelines where applicable to support our clients' regulatory compliance.

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). This product is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere (e.g., nitrogen) in the original packaging to prevent degradation.
