Product Description

Tridodecylmethylammonium Chloride (T1211/TDMAC) CAS No 7173-54-8
Tridodecylmethylammonium Chloride (T1211/TDMAC) is a high-purity quaternary ammonium compound widely employed as a cationic surfactant and efficient phase transfer catalyst. Its distinctive molecular architecture, featuring a positively charged quaternary nitrogen headgroup bonded to one methyl and three long dodecyl (C12) chains, imparts strong lipophilic character and exceptional surface activity. In biomedical applications, TDMAC is particularly valued for its ability to form stable ionic complexes with anionic pharmaceuticals such as heparin and antibiotics, enabling the passive loading and controlled release of bioactive agents from polymeric medical device surfaces. This makes it an industry-standard pretreatment for coating catheters, vascular grafts, and implants to enhance hemocompatibility and reduce infection risks. Beyond healthcare, it serves as a versatile reagent in organic synthesis, facilitating reactions between immiscible phases, and in material science for modifying surfaces and developing ion-selective electrodes.

Application
T1211/TDMAC is used as a phase transfer catalyst in organic synthesis.
1. Biomedical Coating
TDMAC serves as a highly effective cationic pretreatment layer for medical devices, utilizing its positively charged quaternary ammonium groups to ionically bond anionic pharmaceuticals such as heparin and antibiotics onto polymer surfaces. This electrostatic interaction creates a stable, non-covalent complex that enables the passive loading of bioactive agents onto materials like catheters, vascular grafts, and implants. The coated devices benefit from controlled local drug release, significantly reducing the risk of post-surgical infections and thrombus formation. This technology is particularly valuable for improving hemocompatibility in blood-contacting devices without altering the bulk material properties.
2. Phase Transfer Catalysis
As a quaternary ammonium phase transfer catalyst, TDMAC facilitates chemical reactions between reagents located in immiscible aqueous and organic phases by transporting reactive anions across the liquid-liquid interface. Its three long dodecyl chains impart strong lipophilic character, allowing the catalyst to solubilize inorganic salts into organic solvents while the cationic center carries reactive species into the organic phase. This mechanism dramatically increases reaction rates, improves product yields, and enables milder reaction conditions in applications such as alkylations, substitutions, and polymerizations. The catalyst can be easily recovered and recycled in many industrial processes, offering both economic and environmental benefits.
3. Material Science & Research
In advanced material science applications, TDMAC functions as a versatile surface-modifying agent for developing functional interfaces and specialized analytical devices. It is commonly employed in the fabrication of ion-selective electrodes and electrochemical sensors, where its cationic nature contributes to membrane selectivity and signal stability. Researchers utilize TDMAC to introduce positive charges onto carbon-based materials like graphene, enabling studies of modified electrocatalytic activity and enhanced composite material properties. The compound also demonstrates utility as an antimicrobial additive in polymer formulations and as an emulsifying surfactant in specialized colloidal systems.
