Ipr in chemistry
In organic chemistry, propyl is a three-carbon alkyl substituent with chemical formula −CH2CH2CH3 for the linear form. This substituent form is obtained by removing one hydrogen atom attached to the terminal carbon of propane. A propyl substituent is often represented in organic chemistry with the symbol Pr (not to be confused with the element praseodymium).

This happens because you can always rotate a Me, Et, or iPr group in a chair conformation so that a H atom points over the middle of the ring. chuck cowell obituary
