Description

Omiganan is a synthetic cationic antimicrobial peptide (AMP) with the CAS number 204248-78-2, representing a significant class of compounds designed to combat microbial resistance. Its primary value lies in its broad-spectrum activity against bacteria, fungi, and other pathogens, making it a potent agent for infection control. This product is essential for pharmaceutical R&D, particularly in developing novel topical antiseptics, medical device coatings, and preservative systems for personal care formulations.

Application

• Development of topical antiseptic formulations for skin preparation prior to surgery or catheter insertion.
• Research into antimicrobial coatings for medical devices and implants to prevent biofilm formation.
• Active ingredient in preservative systems for cosmetics and personal care products.
• Investigational use in veterinary medicine for treating skin and mucosal infections.
• Study of novel mechanisms to overcome multidrug-resistant bacterial strains (e.g., MRSA).
• Component in wound care and dermatological product development.

Quality Control

Our Omiganan is produced under strict quality management systems to ensure batch-to-batch consistency and high purity for research and development purposes. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles. We support compliance with relevant guidelines for pharmaceutical intermediates and active substance development.

Storage

Preserve in a tightly closed container, protected from light. Store at controlled room temperature (15-25°C) or as indicated on the label. This material is hygroscopic (moisture-sensitive) and must be kept in a dry environment. For long-term storage, consider desiccants or inert atmosphere to maintain stability.
