2,6-Dimethylnaphthalene is mainly used for the preparation of 2,6-naphthalenedicarboxylic acid by oxidation of 2,6-dimethylnaphthalene in the liquid phase. 2,6-Naphthalenedicarboxylic acid is a monomer for the production of high-performance polymers, in particular poly (ethylene-2,6-naphthalene dicarboxylate) or shorter polyethylene naphthalate (PEN). [4]
It was first prepared by Robert Evert and Victor Merz in 1876 by hydrolysis of 2,6-dicyanonaphthalene. [2] [3] 1,8-Naphthalenedicarboxylic acid can be isomerized to 2,6-naphthalenedicarboxylic acid via the intermediacy of the dipotassium dicarboxylates. [2] It is also produced by oxidation of 2,6-diisopropylnaphthalene. [4]
Shulgin explains in his book that DMMDA has 6 isomers similar to TMA. [1] DMMDA-2 is the only other isomer that has been synthesized as of yet. DMMDA-3 could be made from exalatacin (1-allyl-2,6-dimethoxy-3,4-methylenedioxybenzene). Exalatacin can be found in the essential oil of both Crowea exalata and Crowea angustifolia var. angustifolia.

DMMDA-2 is a bioactive phenethylamine discussed by Alexander Shulgin in his book PiHKAL (Phenethylamines i Have Known And Loved); however, he was not the first to synthesize it. [1] Shulgin comments in his book that a 50 milligram dose of DMMDA-2 produces similar effects to 3,4-methylenedioxy-1-α-methylphenylethylamine . [ 1 ]
Diaminonaphthalene describes several isomers containing naphthalene substituted with two amine groups (NH 2), also called naphthalenediamines. All isomers are white solids that tend to air-oxidize. The 2,3-, 1,5-, and 1,8- derivatives have attracted most attention. 1,2-Diaminonaphthalene 938-25-0 [1] 1,3-Diaminonaphthalene 24824-28-0 [2]
DMCM (methyl 6,7-dimethoxy-4-ethyl-β-carboline-3-carboxylate) is a drug from the β-carboline family that induces anxiety and convulsions by acting as a negative allosteric modulator of GABA A receptors — functionally opposite to benzodiazepines and related drugs which are positive allosteric modulators — and is used in scientific research for these properties to test new anxiolytic and ...
Synthesis of symmetric and unsymmetric NDIs. NTCDI is redox-active, forming stable radical anions at –1.10 V vs. Fc/Fc + in Dichloromethane. [5] Its ability to accept electrons reflects the presence of an extended conjugated ring system and the electron withdrawing groups (carbonyl centers).
1,8-Bis(dimethylamino)naphthalene is an organic compound with the formula C 10 H 6 (NMe 2) 2 (Me = methyl). It is classified as a peri-naphthalene , i.e. a 1,8-disubstituted derivative of naphthalene .
