Product Overview
Cetyltrimethylammonium bromide (CTAB) AR grade is a high-purity cationic surfactant widely used in laboratory settings for its exceptional emulsifying, dispersing, and solubilizing properties. This analytical reagent-grade compound ensures minimal impurities, making it ideal for critical applications where precision and reliability are essential. With a molecular formula of C19H42BrN, CTAB exhibits strong antimicrobial activity and is commonly employed in biochemical assays, nanoparticle synthesis, and DNA extraction protocols. Its white crystalline powder form dissolves readily in water, forming clear solutions that maintain stability across a broad pH range. The AR grade designation guarantees consistent performance, meeting stringent quality standards for research and analytical procedures. Whether used as a phase transfer catalyst or a detergent in protein studies, CTAB delivers reproducible results, making it a staple in modern laboratories. Store in a cool, dry place to preserve its integrity and extend shelf life.
FAQs
