Los isomeros son compuestos que tienen la misma formula molecular pero diferente formula estructural y, por tanto, diferentes propiedades.

La isometria es una propiedad de ciertos compuestos quimicos que con igual formula quimica, es decir, iguales proporciones relativas de los atomos que conforman su molecula, presentan estructuras moleculares distintas y, por ello, diferentes propiedades.

Objectives The aim of this research was to develop an efficient, rapid, low-cost spectrophotometric procedure for the quantification of oxygenated monoterpenes in essential oil and derivate products and formulations of creams and gel- creams, using carvacrol as standard substance.

Um outro tipo interessante de atropoisomerismo foi relatado por Randall et al. Working standard solutions were prepared immediately after filtration, before use by suitable dilutions of the corresponding stock solutions 1.

For the determination of LOEO at carvacrol equivalent in the gel-cream formulation was developed a derivative spectrophotometric method using zero crossing first derivative D1 methodology. Atropisomerism has been originally described in orto -functionalyzed biphenyl derivatives, but a lot of other organic functionalities can present this structural phenomenon, characterized by the presence of chiral properties in compounds that don’t present classical stereogenic centers.
