Description

Echinocandin D CAS NO 71018-13-8 is a potent antifungal lipopeptide belonging to the echinocandin class of natural products. It serves as a critical intermediate and reference standard in the research and development of novel antifungal agents, particularly for targeting fungal cell wall synthesis. This compound is essential for pharmaceutical R&D laboratories, biotechnology companies, and academic institutions focused on developing treatments for systemic fungal infections.

Application

• Pharmaceutical Reference Standard: Used as a high-purity standard for analytical method development, validation, and quality control in antifungal drug manufacturing.
• Biochemical Research: Employed in studies investigating the mechanism of action of echinocandin-class drugs against β-(1,3)-D-glucan synthase.
• Antifungal Drug Development: Serves as a key intermediate or lead compound for the semi-synthesis and structure-activity relationship (SAR) studies of new antifungal candidates.
• Microbiology Studies: Utilized in *in vitro* assays to determine the susceptibility of pathogenic fungal strains, such as *Candida* and *Aspergillus* species.

Quality Control

Our Echinocandin D is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and MS for structural confirmation, and microbiological assays for potency. Certificates of Analysis (COA) detailing all specifications and test results are available upon request to ensure full traceability and compliance with your research or development requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C. Due to its hygroscopic nature, the product should be handled under a dry, inert atmosphere and allowed to equilibrate to room temperature before opening to prevent moisture condensation.
