Ultraviolet and infrared spectrophotometric analysis of an insect-repellent mixture was written by Sassaman, Warren A.;Cohen, S. P.. And the article was included in Applied Spectroscopy in 1954.Computed Properties of C9H20O2 The following contents are mentioned in the article:

A spectrophotometric procedure employing measurements in both the ultraviolet and infrared regions was developed to determine the concentrations of N-butylacetanilide, benzyl benzoate, 2-ethyl-2-butyl-1,3-propanediol, and Tween 80, in a mixture containing only these 4 components. The first 2 components have relatively strong absorptivities in the ultraviolet at 227.5 and 280.3 millimicrons, while the latter 2 have absorption bands at the infrared wave lengths, 8.99 and 9.60 microns. By substituting the absorptivities at these wave lengths in a set of 4 simultaneous equations, the percentage of each component in an insect-repellent mixture is calculated This study involved multiple reactions and reactants, such as 2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4Computed Properties of C9H20O2).

2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Computed Properties of C9H20O2

2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4) belongs to alcohols. Because alcohols are easily synthesized and easily transformed into other compounds, they serve as important intermediates in organic synthesis. Alcohols may be oxidized to give ketones, aldehydes, and carboxylic acids. These functional groups are useful for further reactions. Oxidation of organic compounds generally increases the number of bonds from carbon to oxygen (or another electronegative element, such as a halogen), and it may decrease the number of bonds to hydrogen.Application In Synthesis of 2-Butyl-2-ethylpropane-1,3-diol

In this study, Hawthorn oligomic procyanidins extracts (HPOE) were evaluated for their anticancer activity on colorectal cancer. Our results showed that HPOE arrested HCT116 cells cycle at G2/M phase through P53-Cyclin B pathway and promoted apoptosis partly via mitochondrial (Caspase 9-Caspase 3) and death receptor (Caspase 8-Caspase 3) pathways. Meanwhile, it was found that HPOE aggravated HCT116 cells death through lysosomal vacuolation, which was verified by inhibitor/activator of P53-ILC3 signaling pathway. Taken together, HPOE exerted anticancer effects which lays the foundation for the development of functional foods for clin. colon cancer patients. This study involved multiple reactions and reactants, such as (2R,2’R,3R,3’R,4R)-2,2′-Bis(3,4-dihydroxyphenyl)-[4,8′-bichromane]-3,3′,5,5′,7,7′-hexaol (cas: 29106-49-8Safety of (2R,2’R,3R,3’R,4R)-2,2′-Bis(3,4-dihydroxyphenyl)-[4,8′-bichromane]-3,3′,5,5′,7,7′-hexaol).

Ruthenium(II)-catalyzed deoxygenation of ketones was written by Gui, Ruohua;Li, Chao-Jun. And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2022.Name: 4,4′-Methylenediphenol The following contents are mentioned in the article:

The classical Wolff-Kishner reduction plays a key role in organic synthesis to convert carbonyl functionalities into methylene groups; however, it generally requires harsh reaction conditions and a strategy with wider applications demands further development. Herein, a ruthenium-catalyzed Wolff-Kishner type reduction of ketones is developed with 31 examples under mild conditions. This strategy tolerates aryl and alkyl ketones with reactive functional groups including halogens, hydroxyls, carboxylic acid, unsaturated functional groups, and so on. The corresponding methylene products were obtained in 32% to 95% yields while using water or methanol as solvents. This study involved multiple reactions and reactants, such as 4,4′-Methylenediphenol (cas: 620-92-8Name: 4,4′-Methylenediphenol).

4,4′-Methylenediphenol (cas: 620-92-8) belongs to alcohols. A strong base can deprotonate an alcohol to yield an alkoxide ion (R―O−). For example, sodamide (NaNH2), a very strong base, abstracts the hydrogen atom of an alcohol. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.Name: 4,4′-Methylenediphenol

The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers. This reaction is effective only with methanol, ethanol, and other simple primary alcohols.Related Products of 27208-80-6
