1-​tert-​Butyl-​3,​5-​dimethylbenzene

1-​tert-​Butyl-​3,​5-​dimethylbenzene (Xylometazoline EP Impurity D) is a reagent used in the synthesis of polyarenes as oligonapthalene derivatives as well as in the preparation of arylsulfur trifluorides from diaryl disulfides. Xylometazoline derivative, a vasoconstrictor involved in signal transduction, also used as a nasal decongestant. May be used in treatments involving ischemic injury due to the ability to shift energy metabolism from mitochondrial to glycolysis (2).
