Description

Anidulafungin is a semi-synthetic echinocandin antifungal agent derived from a fermentation product of *Aspergillus nidulans*. This compound is a critical active pharmaceutical ingredient (API) valued for its potent fungicidal activity against *Candida* species, including azole-resistant strains. It is primarily required by pharmaceutical manufacturers for the formulation of injectable antifungal medications used in hospital settings to treat serious systemic fungal infections.

Application

• Pharmaceutical API: Primary use as the active ingredient in sterile injectable formulations for the treatment of candidemia and other forms of invasive candidiasis.
• Hospital Medication: Formulated into intravenous (IV) solutions for clinical administration to hospitalized patients with compromised immune systems.
• Antifungal Research: Serves as a key reference standard and biochemical tool in microbiological and pharmacological research on echinocandin mechanisms of action.
• Drug Development: Used in preclinical and clinical studies for developing new antifungal therapies and combination treatments.
• Quality Control Standards: Employed as a certified reference material (CRM) in analytical laboratories for method validation and assay calibration.

Quality Control

Our Anidulafungin is manufactured under strict quality management systems. It is tested to meet high-purity standards suitable for pharmaceutical applications, with specifications aligned with major pharmacopoeial guidelines. A comprehensive Certificate of Analysis (COA), detailing results for identity, purity, assay, and impurity profiles (including related substances and residual solvents), is provided with each batch to ensure regulatory compliance and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider conditions under an inert atmosphere.
