pentanoln.

Brit.

/ˈpɛntənɒl/, U.S.

/ˈpɛn(t)əˌnɔl/,

/ˈpɛn(t)əˌnɑl/

Origin: Formed within English, by derivation. Etymons: pentane n., -ol suffix.

Etymology: < pentane n. + -ol suffix. Compare slightly earlier methanol n., butanol n.

Chemistry.

Any saturated monohydric alcohol of the formula C₅H₁₁OH, of which several isomeric forms exist; spec. (also n-pentanol or 1-pentanol) the primary straight-chain alcohol CH₃(CH₂)₃CH₂OH (n-amyl alcohol).
