N-butane, such as Puretane butane, is highly refined and is the type of butane that we normally think about when we hear the term. Stars. Using isobutane, gasoline-grade "blendstocks" are generated with high branching for good combustion characteristics. When compared to the conventional structural formula, it can be easily noticed that a condensed formula is less lengthy.
