n-pentane

Also known as R-601

Pentane is an organic compound with the formula C5H12—that is, an alkane with five carbon atoms. The term may refer to any of three structural isomers, or to a mixture of them: in the IUPAC nomenclature, however, pentane means exclusively the n-pentane isomer, in which case pentanes refers to a mixture of them; the other two are called isopentane (methylbutane) and neopentane (dimethylpropane). Cyclopentane is not an isomer of pentane because it has only 10 hydrogen atoms where pentane has 12.

AI overview

N-pentane is a simple organic compound made of five carbon atoms and twelve hydrogen atoms (C5H12), belonging to a group of molecules called alkanes. It's one of three possible structural arrangements of these atoms, though "pentane" in scientific naming specifically refers to the n-pentane form.

Pentanes are components of some fuels and are employed as specialty solvents in the laboratory. Their properties are very similar to those of butanes and hexanes.
