Note If these trivial names are used as a basis for naming derivatives or stereoisomers, the derived trivial name must make the nature of the modification completely clear and is preferably accompanied at first mention by the full systematic name. For example, in steroid papers epi is often used with trivial names to denote inversion at one centre; the name 11-epicortisol defines the compound fully since cortisol is already defined as the 11-alcohol; but the name epicortisol does not define the compound and is inadequate.
