Heptene is a higher olefin, or alkene with the formula C 7 H 14. The commercial product is a liquid that is a mixture of isomers . It is used as an additive in lubricants, as a catalyst , and as a surfactant .
Heptane or n-heptane is the straight-chain alkane with the chemical formula H 3 C(CH 2) 5 CH 3 or C 7 H 16.When used as a test fuel component in anti-knock test engines, a 100% heptane fuel is the zero point of the octane rating scale (the 100 point is 100% iso-octane).
With cycloheptene, the cis-isomer is always assumed but the trans-isomer does also exist.One procedure for the organic synthesis of trans-cycloheptene is by singlet photosensitization of cis-cycloheptene with methyl benzoate and ultraviolet light at −35 °C. [2]
Heptanone may refer to the following ketones with seven carbon atoms the formula C 7 H 14 O: . 2-Heptanone (Methyl amyl ketone) . 5-Methyl-2-hexanone (Methyl isoamyl ketone); 4-Methyl-2-hexanone (Methyl 2-methylbutyl ketone)

A lot of haptens are comprised in different kinds of drugs, pesticides, hormones, food toxins etc. Most important factor is the molecular mass, which is <1000 Da. [8]The first researched haptens were aniline and its carboxyl derivatives (o-, m-, and p-aminobenzoic acid).
