Description

Foscarnet Sodium CAS NO 63585-09-1 is the sodium salt of phosphonoformic acid, a potent antiviral agent. It is a critical active pharmaceutical ingredient (API) valued for its selective inhibition of viral DNA polymerases. This compound is essential for manufacturers in the pharmaceutical industry developing antiviral medications, particularly for the treatment of severe cytomegalovirus (CMV) infections and herpesvirus infections in immunocompromised patients.

Application

• Antiviral Pharmaceutical API: Primary active ingredient in injectable formulations for systemic antiviral therapy.
• Treatment of CMV Retinitis: Used in medications for cytomegalovirus retinitis in patients with AIDS.
• Acyclovir-Resistant HSV Infections: Therapeutic option for herpes simplex virus infections unresponsive to standard treatments.
• Research & Development: Reference standard and building block in virology research and new antiviral drug discovery.
• Hospital Compounding: Used in specialized pharmacy compounding for tailored patient treatments.
• Veterinary Antiviral Applications: Potential use in developing antiviral treatments for animal health.

Quality Control

Our Foscarnet Sodium is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets high-purity standards suitable for pharmaceutical use. We provide full traceability and Certificates of Analysis (COA) are available for all shipments, detailing purity, identity, and impurity profiles. Production can be aligned with current Good Manufacturing Practice (cGMP) principles for API manufacture upon request.

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 material is hygroscopic (moisture-sensitive) and must be kept in a dry environment to prevent degradation. For long-term storage, consider desiccated conditions.
