6-(3-Chlorophenyl)-2-[3-(2,5-dimethyl-1H-pyrrol-1-yl)thiophen-2-yl]pyrazolo[1,5-a]pyrimidin-7-amine (C22H18ClN5S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
