C9 aromatic hydrocarbons, named for their nine carbon monomers, exhibit a distinct aromatic odor and typically possess a Gardner color scale rating of 6 to 10, ranging from dark yellow to dark brown. They are insoluble in water, as well as in low alcohols and ketones. However, they are soluble in aliphatic hydrocarbons and chlorinated hydrocarbon solvents.
