Description
Octadecy trimethyl ammonium bromide, also known as C18TAB, is a white powder chemical compound with the formula C23H48BrN. It is a quaternary ammonium salt derived from octadecyltrimethylammonium, which is a type of cationic surfactant. Octadecy trimethyl ammonium bromide is known for its amphiphilic properties, which means it has both hydrophilic (water-attracting) and hydrophobic (water-repelling) characteristics.
Uses
Used in Pharmaceutical Industry:
Octadecy trimethyl ammonium bromide is used as a Dynamin I inhibitor for various pharmaceutical applications. Dynamin I is a protein involved in the regulation of vesicular trafficking, and its inhibition can have therapeutic effects on certain conditions.
Used in Material Science:
In the field of material science, Octadecy trimethyl ammonium bromide is used as a surfactant. Its surfactant properties allow it to lower the surface tension between two liquids or between a liquid and a solid, making it useful in the preparation of polyoxomolybdate-surfactant hybrid layered crystals.
Used in Chromatography:
Octadecy trimethyl ammonium bromide is also utilized as a surface modifier in liquid chromatography. Its cationic nature enables it to interact with various compounds, improving the separation and analysis of different substances in complex mixtures.

Purification Methods
Crystallise it from EtOH or H2O (solubility is 1 in 1000parts). It is very soluble in Me2CO. It is a bactericide. [Sheldon et al. J Am Chem Soc 68 754 1946, Grieger & Kraus J Am Chem Soc 70 3805, 38007, Beilstein 4 IV 827.]
Check Digit Verification of cas no
The CAS Registry Mumber 1120-02-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,2 and 0 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1120-02:
(6*1)+(5*1)+(4*2)+(3*0)+(2*0)+(1*2)=21
21 % 10 = 1
So 1120-02-1 is a valid CAS Registry Number.

Odd-even effect and unusual behavior of dodecyl-substituted analogue observed in the crystal structure of alkyltrimethylammonium-[Ni(dmit) 2]- salts

A series of [Ni(dmit)2]- (dmit: 1,3-dithiole-2- thione-4,5-dithiolato) salts of alkyltrimethylammonium (Cn: n represents the alkyl chain length; n = 3 and 518) have been prepared and analyzed by X-ray structural analysis. All complex salts have been found to be composed of alternate sheets of [Ni(dmit)2]- anions and sheets of cations with a pronounced interdigitation of the alkyl chains. However, molecular arrangement differed between (C3)[Ni(dmit)2] and other (Cn)[Ni(dmit)2] (n = 518). Adjacent cations were aligned along the long axis of [Ni(dmit)2]- anion in C3 complex salt, while in others (C5-C18 complex salts), they were aligned toward the short axis. Such a difference in arrangement arose from correlativity between the lengths of the long axis of cation and anion, namely CLCA. Furthermore, relative orientation between the alkyl chain of cation and [Ni(dmit)2]- anion differed between the odd- and even-numbered cations for C10-C18. Whereas the plane of alkyl chain for odd-numbered cation was normal to the plane of [Ni(dmit)2]- anion, that of even-numbered cation was parallel. It was also found that C12 analog behaved like odd-numbered cations. However, in C12 salt, the end methyl group of the dodecyl group adopted unusual end-gauche conformation.
