pentadecanen.

Brit.

/ˈpɛntədᵻkeɪn/, U.S.

/ˈpɛn(t)ədəˌkeɪn/

Origin: Formed within English, by derivation. Etymons: penta- comb. form, deca- comb. form, -ane suffix² 2

Etymology: < penta- comb. form + deca- comb. form + -ane suffix² 2. Compare French pentadécane (1886 or earlier), German Pentadecan (1903 or earlier), and also Byzantine Greek πενταδεκα- , variant (in πενταδεκαέτης ) of ancient Greek πεντεκαιδεκα- , combining form (in e.g. πεντεκαιδεκαετής fifteen years old) of πεντεκαίδεκα fifteen. Compare pentadecyl n., pentadecyne n.

Chemistry.

Any of a series of saturated hydrocarbons (alkanes) with the formula C₁₅H₃₂, esp. (also n- pentadecane) the unbranched isomer, CH₃(CH₂)₁₃CH₃, a liquid present in petroleum.
