Dibenzothiophene (DBT, diphenylene sulfide) is the organosulfur compound consisting of two benzene rings fused to a central thiophene ring. It has the chemical formula C 12 H 8 S. It is a colourless solid that is chemically somewhat similar to anthracene .
It contains 87.5–91% by volume of absolute ethyl alcohol. The rest consists of water and the denaturants, with or without color additives, and perfume oils. Rubbing alcohol contains in each 100 ml more than 355 mg of sucrose octaacetate or more than 1.40 mg of denatonium benzoate. The preparation may be colored with one or more color additives.
Dess–Martin periodinane (DMP) is a chemical reagent used in the Dess–Martin oxidation, oxidizing primary alcohols to aldehydes and secondary alcohols to ketones. [1] [2] This periodinane has several advantages over chromium- and DMSO-based oxidants that include milder conditions (room temperature, neutral pH), shorter reaction times, higher yields, simplified workups, high chemoselectivity ...
Cinnamyl alcohol has a distinctive odor described as "sweet, balsam, hyacinth, spicy, green, powdery, cinnamic" and is used in perfumery [4] and as a deodorant. Cinnamyl alcohol is the starting material used in the synthesis of reboxetine .
It is bifunctional, containing both a tertiary amine and primary alcohol functional groups. It is a colorless viscous liquid. It is used in skin care products for improving skin tone and also taken orally as a nootropic. It is prepared by the ethoxylation of dimethylamine. [2]
Benzyl benzoate can be a skin irritant when used as a topical scabicide. [7] Overdose can result in blistering and hives or a rash can occur as an allergic reaction. [12] [13] As an excipient in some testosterone-replacement injectable medications, benzyl benzoate has been reported as a cause of anaphylaxis in a case in Australia. [14]
The extended conjugation of the acrylate portion of the molecule absorbs UVB and short-wave UVA (ultraviolet) rays with wavelengths from 280 to 320 nm, [1] protecting the skin from direct DNA damage. The ethylhexanol portion is a fatty alcohol , adding emollient and oil-like (water resistant) properties.
Benzyl mercaptan is used for S-alkylation to give benzylthioethers. [3]It has been used as a source of the thiol functional group in organic synthesis.Debenzylation can be effected by dissolving metal reduction: [4]
