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 ...
The Dess–Martin oxidation is an organic reaction for the oxidation of primary alcohols to aldehydes and secondary alcohols to ketones using Dess–Martin periodinane. [ 1][ 2] It is named after the American chemists Daniel Benjamin Dess and James Cullen Martin who developed the periodinane reagent in 1983. The reaction uses a hypervalent ...
Dextromethorphan does not have a significant affinity for the mu-opioid receptor activity typical of morphinan compounds and exerts its therapeutic effects through several other receptors. [8] In its pure form, dextromethorphan occurs as a white powder. [9] When exceeding approved dosages, dextromethorphan acts as a dissociative hallucinogen.
Dimethyl phthalate (DMP) is an organic compound and phthalate ester. it is a colourless and oily liquid that is soluble in organic solvents, [4] but which is only poorly soluble in water (~4 g/L). It is used in a variety of products and is most commonly used as insect repellent such as ectoparasiticide for mosquitoes and flies for animal ...
2,2-Dimethoxypropane ( DMP) is an organic compound with the formula (CH 3) 2 C (OCH 3) 2. A colorless liquid, it is the product of the condensation of acetone and methanol. DMP is used as a water scavenger in water-sensitive reactions. Upon acid-catalyzed reaction, DMP reacts quantitatively with water to form acetone and methanol. [2]
Psychedelia. N,N-Dimethyltryptamine ( DMT or N,N-DMT) is a substituted tryptamine that occurs in many plants and animals, including humans, and which is both a derivative and a structural analog of tryptamine. [ 4] DMT is used as a psychedelic drug and prepared by various cultures for ritual purposes as an entheogen.
2,4-Dinitrophenylhydrazine ( 2,4-DNPH or DNPH) is the organic compound C 6 H 3 (NO 2) 2 NHNH 2. DNPH is a red to orange solid. It is a substituted hydrazine. The solid is relatively sensitive to shock and friction. For this reason DNPH is usually handled as a wet powder. DNPH is a precursor to the drug Sivifene .
