Cetyltrimethylammonium Bromide is a cationic detergent suitable for the isolation of high molecular weight DNA in plants and other organisms. Cetyltrimethylammonium Bromide, an organic bromide salt and quaternary ammonium salt, serves as a vital component in the potentiometric titration of perchlorate using ion-selective electrodes. It functions as a titrant, enabling the precise measurement of perchlorate levels through a specialized analytical technique.
