Dimethoxytrityl, often abbreviated DMT, is a protecting group widely used for protection of the 5'-hydroxy group in nucleosides, particularly in oligonucleotide synthesis. [ 1 ] It is usually bound to a molecule, but can exist as a stable cation in solution, where it appears bright orange.
L n M−OH + H + ⇌ L n M−OH + 2 where L n is the ligand complement on the metal M. Thus, aquo ligand is a weak acid, of comparable strength to acetic acid (pK a of about 4.8). [6] In principle but not very commonly, metal hydroxides undergo deprotonation, yielding oxo complexes: L n M−OH ⇌ L n M=O − +H + Characteristically, hydroxide ...
6-MeO-DMT, or 6-methoxy-N,N-dimethyltryptamine, also known as 6-OMe-DMT, is a serotonergic drug of the tryptamine family. [ 1 ] [ 2 ] It is the 6- methoxy derivative of the serotonergic psychedelic N , N -dimethyltryptamine (DMT) and is a positional isomer of the serotonergic psychedelic 5-MeO-DMT .
Protecting groups cleaved by heavy metal salts or their complexes. Photolabile protecting groups; Double-layered protecting groups; Various groups are cleaved in acid or base conditions, but the others are more unusual. Fluoride ions form very strong bonds to silicon; thus

DMT can also be made by a different route, namely direct esterification of terephthalic acid with methanol. The dimethyl terephthalate that is formed is then purified by distillation. Even terephthalic acid of low purity may be used in this method. C 8 H 6 O 4 + 2CH 3 OH → C 10 H 10 O 4 + 2 H 2 O. in the presence of o-xylene at 250–300 °C.
5-MeO-DMT is lipophilic and is thought to easily cross the blood–brain barrier. [2] Accordingly, 5-MeO-DMT readily accumulates in the brain in animals with levels higher than in blood. [2] This is in notable contrast to bufotenin (5-HO-DMT or N,N-dimethylserotonin) and serotonin (5-HT), which are hydrophilic and peripherally selective. [2 ...
A chemical depilatory is a cosmetic preparation used to remove hair from the skin.Common active ingredients are salts of thioglycolic acid and thiolactic acids.These compounds break the disulfide bonds in keratin and also hydrolyze the hair so that it is easily removed.
