Understanding Octadecyl: A Versatile Modifying Group in Organic Chemistry

Octadecyl is a chemical compound with the formula C18H37. It is a long-chain alkyl group that is commonly used in organic chemistry as a modifying group in various reactions. The name "octadecyl" comes from the fact that the group has 18 carbon atoms.

Octadecyl is a hydrophobic (water-repelling) group, and it is often used to modify the properties of molecules by adding a hydrophobic tail to them. For example, octadecyl groups can be added to polymers to make them more water-repellent, or to proteins to increase their stability in hydrophobic environments.

In summary, octadecyl is a chemical compound with 18 carbon atoms that is commonly used as a modifying group in organic chemistry to add hydrophobicity to molecules.
