Description
Cetyltrimethylammonium hydrogensulfate, also known as cetrimide or cetylpyridinium chloride, is a quaternary ammonium compound that acts as a cationic surfactant. It is characterized by its amphiphilic nature, with a long hydrophobic alkyl chain and a positively charged hydrophilic head. This unique structure allows it to form micelles in aqueous solutions and interact with various organic and inorganic substances.
Uses
Used in Organic Synthesis:
Cetyltrimethylammonium hydrogensulfate is used as a surfactant for organic transformations in aqueous media. Its cationic nature enables it to stabilize and solubilize organic substrates, facilitating their reactions in water.
Used in Rhodium(I)-Catalyzed Asymmetric Hydrogenation:
In the Rhodium(I)-catalyzed asymmetric hydrogenation of (Z)-methyl-α-acetamidocinnamate, cetyltrimethylammonium hydrogensulfate is used as a phase-transfer agent. It helps to dissolve the organic substrate in the aqueous phase, promoting the reaction and enhancing the enantioselectivity of the hydrogenation process.
Used in Asymmetric Palladium-Catalyzed Alkylation:
In the asymmetric palladium-catalyzed alkylation of 1,3-diphenyl-2-propenyl acetate with dimethyl malonate, cetyltrimethylammonium hydrogensulfate is employed as a surfactant. It aids in the solubility and reactivity of the organic reactants, leading to improved yields and selectivity in the alkylation reaction.
Check Digit Verification of cas no
The CAS Registry Mumber 68214-07-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,2,1 and 4 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 68214-07:
(7*6)+(6*8)+(5*2)+(4*1)+(3*4)+(2*0)+(1*7)=123
123 % 10 = 3
So 68214-07-3 is a valid CAS Registry Number.
