Tridodecylmethylammonium Chloride (T1211/TDMAC)

CAS 7173-54-8

Tridodecylmethylammonium Chloride (CAS 7173-54-8) is a high-purity quaternary ammonium compound widely recognized as an effective cationic surfactant and phase transfer catalyst. Featuring a positively charged nitrogen headgroup bonded to one methyl and three long dodecyl chains, this white to off-white crystalline powder exhibits strong lipophilic character and excellent surface activity. It is extensively used in biomedical applications as a heparin or antibiotic coating agent for medical devices such as catheters and vascular grafts, forming stable ionic complexes that enhance hemocompatibility and prevent infections. In organic synthesis, it serves as a reliable phase transfer catalyst, facilitating reactions between immiscible phases to improve yields and reaction rates. Additionally, it finds applications in material science for developing ion-selective electrodes and functional surfaces. With a typical purity of ≥98% and solubility in organic solvents like ethanol and DMSO, TDMAC offers versatility and consistent performance across pharmaceutical, chemical, and research industries.

>> Main Uses

Tridodecylmethylammonium Chloride (T1211/TDMAC, CAS 7173-54-8) serves three primary industrial and research functions. In biomedical applications, it functions as a cationic pretreatment coating for medical devices such as catheters, vascular grafts, and implants, where its positively charged groups ionically bond anionic pharmaceuticals like heparin and antibiotics to surfaces, enabling controlled local drug release that enhances hemocompatibility and reduces post-surgical infection risks. As a phase transfer catalyst in organic synthesis, it facilitates reactions between immiscible aqueous and organic phases by transporting reactive anions across interfaces, significantly improving reaction rates, yields, and enabling milder conditions for alkylations, substitutions, and polymerizations. In material science and research, it acts as a versatile surface-modifying agent for developing ion-selective electrodes and electrochemical sensors, introduces positive charges onto carbon-based materials like graphene for electrocatalysis studies, and serves as an antimicrobial additive and emulsifying surfactant in specialized formulations and colloidal systems.
