Description
Heptadecyltrimethylammonium bromide is a quaternary ammonium compound that functions as a cationic surfactant and antistatic agent. It consists of a long hydrocarbon chain (heptadecyl) and three methyl groups attached to a central nitrogen atom, with a bromide anion as a counterion. This chemical is recognized for its ability to reduce surface tension and improve the dispersal of particles, making it a beneficial ingredient in products that require emulsifying, wetting, and conditioning properties.

Used in Hair Conditioners:
HeptadecyltriMethylaMMoniuM BroMide is utilized in hair conditioners as a conditioning agent, helping to detangle and smooth hair, making it more manageable and easier to style.
It is important to handle heptadecyltrimethylammonium bromide with care due to its irritant properties and potential environmental impact.
Check Digit Verification of cas no
The CAS Registry Mumber 21424-24-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,4,2 and 4 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 21424-24:
(7*2)+(6*1)+(5*4)+(4*2)+(3*4)+(2*2)+(1*4)=68
68 % 10 = 8
So 21424-24-8 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.
