Description

Pradimicin B CAS NO 117704-66-2 is a benzonaphthacenequinone antibiotic belonging to the pradimicin family, a class of compounds known for their unique carbohydrate-binding properties. This compound is valued for its potent antifungal activity, particularly against a broad spectrum of pathogenic fungi, including *Candida* species. It serves as a critical reference standard and research-grade material for pharmaceutical R&D, microbiology, and antifungal mechanism studies, enabling the development of novel therapeutic agents and diagnostic tools.

Application

• Pharmaceutical Reference Standard: Used for the qualitative and quantitative analysis of pradimicin-class antibiotics in drug development and quality control laboratories.
• Antifungal Research: Serves as a key investigational compound in microbiological studies to understand mechanisms of action against fungal pathogens.
• Biochemical Research: Employed in studies of carbohydrate-protein interactions due to its lectin-like, mannose-binding activity.
• Lead Compound Development: Acts as a structural template for the semi-synthesis and optimization of new antifungal agents with improved efficacy and safety profiles.
• Academic Research: Utilized in university and institutional labs for studies in medicinal chemistry, mycology, and infectious disease.

Quality Control

Our Pradimicin B is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and reliability for research applications. Each lot is characterized using advanced analytical techniques including HPLC, NMR, and MS to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and related substances is provided with every shipment, supporting compliance with internal quality standards for research and development.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below. Allow the product to equilibrate to room temperature in a dry environment before opening to minimize condensation and potential moisture uptake. The container should be kept in a cool, dry, and well-ventilated area.
