In the title compound, C(15)H(24)O(2), a natural dialkyl-resorcinol commonly named stemphol, the mol-ecules are linked into C(6) and C(2) (2)(4) chains and R(4) (4)(16) rings by inter-molecular O-H⋯O hydrogen bonds, creating mol-ecular sheets parallel to the (010) plane. The alkyl chains are directed orthogonally away from these planes in almost complete extension.

Exogenous ochronosis consists of chronic hyperpigmentation of areas previously treated with topical agents such as hydroquinone, resorcinol, antimalarials and phenol. Early diagnosis allows to promptly suspend the causative agent and it is imperative since the available therapeutic options are scarce and have presented so far unsatisfactory results. Three cases of exogenous ochronosis on the fa...

Naturally occurring dimeric 1,4-benzoquinone derivatives, belamcandaquinones F, G, H, and I, as well as one resorcinol derivative and four known compounds, were isolated from rhizomes of Ardisia gigantifolia. Their structures were established by means of spectroscopic analyses. All compounds were tested against cell lines PC-3, EMT6, A549, Hela, RM-1, and SGC7901 for cytotoxicity in vitro. In c...

Dihydroxybenziphthalocyanine 1, with bulky aryloxy groups, has been synthesized and characterized by X-ray crystallography, NMR and UV/Vis-NIR spectroscopy, and theoretical calculations. Macrocycle 1 is the first example of an aromatic benziphthalocyanine with an 18π-electron structure, and was found to exist as an equilibrium mixture of weakly aromatic and strongly aromatic tautomers. The arom...

Protonation of the reactive intermediate produced in the  reaction between trimethyl phosphite and dimethyl acetylenedicarboxylate or diethyl acetylenedicarboxylate by resorcinol, 5-methylresorcinol, 2,5-dihydroxyacetophenone, 4-chloro-2-methylphenol, 4-chloro-3,5-dimethy-lphenol, 4-hydroxypyridine, 2-hydroxypyridine, 3-hydroxypyridine, or 8-hydroxyquinoline leads to vinylphosphonium salts,...

Phenolic pollutants are very toxic and their removal from aquatic resources is important. Adsorption by activated carbon, AC, the best method for of phenols solutions. However, high cost AC difficulty its regeneration after phenol adsorption puts demand on low price materials. Therefore, sugarcane bagasse as a sustainable, bulky fibrous biomass was selected purpose low-price formation adsorptio...

Mechanoluminescence (ML, also known as triboluminescence or fractoluminescence) is the emission of light due to the application of mechanical stress to a crystal.1 This light is the result of a dielectric breakdown of the intervening gas and the crystal caused by internal electrification at the fracture plane of a piezoelectric crystal. When ML is induced by such mechanical means as grinding, s...
