Didodecyl Dimethyl Ammonium Bromide (D1221-Br)

CAS 3282-73-3

Didodecyl Dimethyl Ammonium Bromide (CAS 3282-73-3) is a high-purity quaternary ammonium compound widely used as a cationic surfactant and phase transfer catalyst. With the CAS number 3282-73-3 and molecular formula C₂₆H₅₆BrN, it appears as a white crystalline powder with excellent solubility in water and ethanol. This versatile product serves as a key component in liposome formulations for non-viral gene delivery, an efficient template for synthesizing mesoporous materials, and an effective cell lysis reagent in diagnostic applications. It also functions as an antistatic agent, emulsifier for nanoparticle preparation, and broad-spectrum disinfectant. Typically offered at ≥98% purity with low free amine content (≤0.1%) and a pH of 6.0-8.0 (1% aqueous solution), it meets the rigorous demands of pharmaceutical, biotechnological, and industrial applications.

>> Main Uses

Didodecyl Dimethyl Ammonium Bromide (D1221-Br, CAS 3282-73-3) is a versatile cationic surfactant and phase transfer catalyst widely employed across chemical, biomedical, and industrial sectors. In organic synthesis, it facilitates two-phase reactions by transferring reactants between aqueous and organic phases and serves as a template agent for directing the structure of mesoporous materials. In biomedical research, it is essential for formulating cationic liposomes used in non-viral gene delivery (DNA/siRNA transfection) and drug encapsulation, and it also acts as a cell lysis reagent in diagnostic kits and biosensor development. Industrially, it functions as an effective emulsifier for nanoparticle preparation, an antistatic agent in plastics and textiles, a broad-spectrum disinfectant with antimicrobial properties, and a surface modifier for clay and organic composite materials to enhance dispersion and compatibility.
