2hidroksüpropil

2-hydroxypropyl is a chemical substituent derived from propane by the addition of a hydroxyl group at the second carbon atom. Its molecular formula is C3H7O. This functional group is commonly found in organic chemistry and can be part of larger molecules, such as in esters, ethers, and alcohols.

When attached to another molecule, the 2-hydroxypropyl group imparts certain properties. The hydroxyl (-OH) group is polar, which can increase the solubility of a molecule in polar solvents like water. It can also participate in hydrogen bonding, influencing intermolecular interactions and physical properties such as boiling point and viscosity.

The 2-hydroxypropyl group is a chiral moiety if the carbon atom to which the hydroxyl group is attached also has three other different substituents. This chirality means that the group can exist as two enantiomers, which are non-superimposable mirror images of each other. Such chiral centers are important in biological systems and in the synthesis of stereospecific compounds.

Common examples of compounds containing the 2-hydroxypropyl group include propylene glycol, which is propane-1,2-diol, and various esters derived from 2-hydroxypropanoic acid (lactic acid). The presence and position of this group significantly influence the chemical reactivity and biological activity of the parent molecule.
