Description
Dimethylditetradecylammonium bromide, also known as DDAB, is a cationic surfactant with the chemical formula (C14H31)2N(CH3)2Br. It is a quaternary ammonium compound that exhibits amphiphilic properties, meaning it has both hydrophilic (water-attracting) and hydrophobic (water-repelling) characteristics. This unique structure allows it to form micelles and interact with various substances, making it useful in a wide range of applications.
Uses
Used in Capillary Electrophoresis:
Dimethylditetradecylammonium bromide is used as a coating agent for the capillary column in the capillary electrophoresis of protein-dye complexes. Its cationic nature helps to reduce the electroosmotic flow and improve the separation efficiency of proteins and dyes.
Used in Drug Delivery Systems:
In the pharmaceutical industry, Dimethylditetradecylammonium bromide is used as a component in the preparation of Fe-porphyrin based pH-sensitive liposomes. These liposomes can be utilized for targeted drug delivery, as they can release their contents in response to specific pH changes, such as those found in tumor environments.
Used in Polymer Science:
Dimethylditetradecylammonium bromide is used as a component in the preparation of ionic polymer complex bulk material, which exhibits optical activity. This property can be exploited in various applications, such as in the development of optical sensors and devices.
Used in Biosensors:
Dimethylditetradecylammonium bromide is also used as a component in the development of tyrosinase-based biosensors. These biosensors are designed for the detection of phenol molecules, which are important environmental and industrial pollutants. The cationic nature of DDAB enhances the sensitivity and selectivity of the biosensor, making it a valuable tool in environmental monitoring and industrial processes.
Check Digit Verification of cas no
The CAS Registry Mumber 68105-02-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,1,0 and 5 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 68105-02:
(7*6)+(6*8)+(5*1)+(4*0)+(3*5)+(2*0)+(1*2)=112
112 % 10 = 2
So 68105-02-2 is a valid CAS Registry Number.

Effect of Cholesterol on the Stereoselective Hydrolysis in Artificial Membrane Systems
Ueoka, Ryuichi,Matsumoto, Yoko
, p. 3774 - 3778 (2007/10/02)
The catalytic efficiency and enantioselectivity for the hydrolysis of p-nitrophenyl N-dodecanoyl-D(L)-phenylalaninate (2b) in the catalytic system of N-tetradecanoyl-L-histidyl-L-leucine (1b) and didodecyldimethylammonium bromide (3a) were enhanced by addition of cholesterol at an optimum temperature (25 deg C).Furthermore, it is suggested that the hydrophobic interaction between reactants in the bilayer membrane system (3a) might be reduced by adding cholesterol on the basis of isokinetic temperature.It is concluded from these results that the fluidity of the artificial bilayer matrix (3a) varies upon addition of cholesterol.
