Description

Rifamycin Sodium is the sodium salt of the potent ansamycin antibiotic, rifamycin. This compound is valued for its broad-spectrum antibacterial activity, particularly against Gram-positive bacteria and mycobacteria. It serves as a critical active pharmaceutical ingredient (API) and intermediate in the production of anti-tuberculosis medications and other specialized antibiotic formulations. Key industries requiring this material include pharmaceutical manufacturing, veterinary medicine, and advanced research in microbiology.

Application

• Pharmaceutical API: Primary use as an active ingredient in injectable and oral antibiotic formulations.
• Anti-Tuberculosis Drugs: Key intermediate in the synthesis of rifampicin and related first-line tuberculosis treatments.
• Veterinary Pharmaceuticals: Used in antibiotic preparations for treating bacterial infections in animals.
• Research & Development: Serves as a standard and building block in microbiological and pharmacological research.
• Hospital Compounding: Utilized in the preparation of specialized antibiotic solutions where commercial formulations are unsuitable.

Quality Control

Our Rifamycin Sodium is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets high-purity standards suitable for pharmaceutical applications. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are provided with every shipment. We support compliance with relevant pharmacopoeial standards (e.g., USP, EP) and regulatory frameworks including cGMP, REACH, and FDA guidelines where applicable.

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 light-sensitive; therefore, containers must be kept tightly sealed in a dry environment and protected from light exposure to maintain stability and potency.
