Usage

General Description

(4-ACETYLPHENYL)-N,N,N-TRIMETHYLMETHANAMINIUM BROMIDE, also known as cetrimonium bromide, is a quaternary ammonium compound commonly used as a surfactant and disinfectant in various industries. It has antiseptic and antimicrobial properties and is often found in hair care products such as shampoos and conditioners, as it helps to prevent the buildup of static electricity and adds volume to the hair. Cetrimonium bromide is also used in the pharmaceutical and cosmetic industries as a preservative and as an ingredient in skin care products due to its ability to solubilize oily substances. Additionally, it has been studied for its potential antiviral and antitumor effects. However, it is important to use cetrimonium bromide with caution, as it can be toxic if ingested or absorbed through the skin in high concentrations.

Photoinduced electron-transfer reactions: Highly efficient cleavage of C-N bonds and photogeneration of tertiary amines

The photocleavage of tertiary amine from tetraphenylborates complexed, via ammonium ions, to various chromophore electron acceptors has been studied by laser-flash photolysis. Electron transfer from the borate anions to acceptor excited states is determined to be the primary photochemical step leading to homolytic C-N bond scission and concomitant formation of the corresponding tertiary amine. This pathway was established by direct observation of p-benzoylbenzyl (7a), p-acetylbenzyl (7b), β-naphthylmethyl (7c), and 7-methoxycoumarin-4-methyl (7d) after laser-flash photolysis from N-(4-benzoyl)benzyl-N,N,N-tributylammonium tetraphenylborate (1a), N-(4-acetyl)benzyl-N,N,N-trimethylammonium tetraphenylborate (1b) N,N,N-tributyl-N-(2-methylnaphthalene)ammonium tetraphenylborate (1c), and N,N,N-tributyl-N-(4-methyl-7-methoxycoumarin)ammonium tetraphenylborate (1d), respectively. The presence of radicals (7a-7d) was also suggested by the reaction products. Comparison of the rate constants for quenching of the triplet states from excited (1a, 1b) and singlet states from (1c, 1d) reveals the efficiency of C-N bond cleavage. Quenching constants in the range of 109-1012 M-1 s-1 were observed. Differences are accounted for in terms of variations in the electron-accepting excited states and structural characteristics of the chromophore acceptors.
