Heneicosane
organic compound
Heneicosane is the organic compound with the formula CH3(CH2)19CH3. It is the straight chain, saturated C21 hydrocarbon. It is a white wax.
Natural occurrence
Heneicosane is used as a pheromone by the queen or king termites in the species Reticulitermes flavipes. It also attracts mosquitoes in the genus Aedes and can be used in mosquito baits. This works in nature as the hydrocarbon is produced in the skin of the larva. A 1:100000 fraction in water is the most attractive, but if the concentration is 1:1000 then mosquitoes are repelled instead. Heneicosane is one of the major components of the safflower flower essential oil (Carthamus tinctorius). All parts of the plant Periploca laevigata contain heneicosane. Rosa damascena flower essential oil contains 5% heneicosane.

Why this record matters
“Heneicosane” is worth following because a concise public description often conceals a longer documentary argument. Here, Heneicosane, organic and compound provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Apr 14, 2026. The linked authority identifier is Q150955. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1000.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
