Description

Poly(N(Delta),N(Delta),N(Delta)-Trimethylornithine) CAS NO 73970-11-3 is a synthetic, cationic polymer derived from the amino acid ornithine, featuring a high density of quaternary ammonium groups. This unique structure provides significant value as a versatile functional material with strong polyelectrolyte and antimicrobial properties. It is primarily needed by researchers and manufacturers in the life sciences, pharmaceutical development, and specialty chemical sectors for applications ranging from biomaterial coatings to gene delivery systems.

Application

• Biomedical Research: Used as a cationic polymer for non-viral gene delivery (transfection) and as a component in drug delivery systems.
• Antimicrobial Coatings: Incorporated into surface coatings for medical devices, textiles, or packaging materials to impart antimicrobial activity.
• Cosmetic & Personal Care: Functions as a conditioning agent and preservative booster in formulations like shampoos and skin creams.
• Water Treatment: Acts as a flocculant or biocide in industrial water treatment processes.
• Paper & Textile Manufacturing: Serves as a retention aid, strengthening agent, or antimicrobial finish.
• Laboratory Reagent: Employed as a standard or building block in organic synthesis and polymer chemistry research.

Quality Control

Our Poly(N(Delta),N(Delta),N(Delta)-Trimethylornithine) is produced under a rigorous quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as molecular weight distribution, degree of quaternization, and residual solvent levels.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product performance.
