Verbena (Vervain)

Normal butanol, also known as n-butanol or 1-butanol, is a four-carbon alcohol that is commonly used as a solvent, chemical intermediate, and fuel. Its chemical formula is C4H10O, and it is an isomer of other butanols, including isobutanol, sec-butanol, and tert-butanol. The term "normal" in the name refers to the fact that the butyl group (C4H9) is attached to the primary carbon atom (the one with only one other carbon atom attached to it) of the alcohol functional group.
