Description

Polynactin is a complex macrolide antibiotic belonging to the polyene class, known for its potent antifungal properties. This compound is critical for applications requiring the inhibition of fungal growth and the protection of materials from biodeterioration. It is primarily utilized by the pharmaceutical, agricultural, and research sectors for the development of antifungal agents and preservative systems.

Application

• Active Pharmaceutical Ingredient (API) in the formulation of topical and systemic antifungal medications.
• Key component in agricultural fungicides for crop protection against fungal pathogens.
• Research and development of novel antimicrobial agents and studying mechanisms of antifungal action.
• Preservative agent in specialized industrial and laboratory settings to prevent microbial contamination.
• Intermediate in the synthesis of more complex polyene antibiotic derivatives.
• Reference standard for quality control and analytical testing in pharmaceutical and chemical laboratories.

Quality Control

Our Polynactin is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets stringent specifications for pharmaceutical and research use. Certificates of Analysis (COA) documenting all test results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a freezer at -20°C to -10°C under an inert atmosphere (e.g., nitrogen or argon) to minimize oxidation. Allow the container to reach room temperature before opening to prevent condensation and moisture ingress.
