Chemical Structure
Description
3-cyclopentyl-8-methyl-5H,6H,7H,8H-[1,2,4]triazolo[4,3-a]pyrazine (C11H18N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
