Natamycin(CAS: 7681-93-8)

Natamycin, with the CAS number 7681-93-8, is a polyene antifungal antibiotic produced by the fermentation of *Streptomyces natalensis*. It has the chemical formula C33H52N10O14 and appears as a white to pale yellow powder. Natamycin is known for its broad-spectrum antifungal activity and is resistant to degradation by many common enzymes, making it suitable for various applications.

Natamycin is primarily used in food preservation as a natural antimicrobial agent, particularly for inhibiting mold and yeast growth on dairy products and other perishables. It also finds applications in pharmaceuticals for treating fungal infections and in research for studying antifungal mechanisms. Additionally, it is used in industrial settings for surface disinfection and biocidal purposes.

Natamycin is generally considered safe when used as intended. It is approved by the FDA and other regulatory bodies for food and pharmaceutical use. However, proper handling is necessary to avoid inhalation or skin contact, especially during manufacturing. Safety data sheets recommend protective measures such as gloves and ventilation to ensure safe use and storage.

Natamycin should be stored in a cool, dry, and dark place, ideally at 2-8°C. It is stable under these conditions and should be kept in a sealed container to prevent moisture and contamination. Avoid exposure to high humidity, direct sunlight, and extreme temperatures to maintain its efficacy and integrity.
