Dioctyldimethylammonium Bromide (D821-Br/DODAB)
CAS 3026-69-5
Dioctyldimethylammonium Bromide (CAS 3026-69-5) is a high-performance quaternary ammonium compound widely recognized for its exceptional surface activity and catalytic efficiency. Supplied as a white to light yellow powder or paste with 70% to 98% active matter, it functions as a versatile cationic surfactant, phase transfer catalyst, and broad-spectrum antimicrobial agent. It excels in stabilizing oil-in-water emulsions, accelerating organic reactions under mild conditions, and providing effective corrosion inhibition for metal surfaces. Its ability to form vesicles and lipid bilayers also makes it valuable in gene delivery, vaccine adjuvant development, and membrane biophysics research. With excellent solubility in organic solvents and customizable technical specifications, this product is suitable for use in personal care formulations, industrial detergents, pharmaceutical synthesis, and disinfectant manufacturing. Sunly factory ensures consistent high purity, low free amine content, and reliable supply for both R&D and bulk industrial applications.
>> Main Uses
Dioctyldimethylammonium Bromide (D821-Br/DODAB, CAS 3026-69-5) is widely used as a cationic surfactant to stabilize emulsions and reduce surface tension in personal care products, industrial detergents, and textile processing. It serves as an efficient phase transfer catalyst in organic synthesis, enabling reactions such as alkylations and esterifications under mild conditions for pharmaceutical intermediates and fine chemicals. As a broad-spectrum antimicrobial agent, it disrupts microbial cell membranes and is incorporated into hospital disinfectants, food processing sanitizers, and antibacterial cleaning formulations. It also functions as a corrosion inhibitor, forming protective films on metal surfaces in cooling systems, oilfield fluids, and metalworking applications. In biochemical research, it self-assembles into vesicles and liposome-like structures for gene delivery, vaccine adjuvant studies, and model membrane systems.
