Because it's an anhydride? The same way a ester/carboxylic acid aren't classified as ketones.
It has an ester FG but the reactivity of anhydrides will be sufficiently different (to esters) that it has it's own group.

It IS an ester, it has an ester FG but the reactivity of anhydrides will be sufficiently different (to esters) that it has it's own group.

Because acid anhydrides are formed by removing a water molecule from two carboxylic acids while esters are (usually) formed by removing a water molecule from an alcohol and a carboxylic acid

haha thank you. For some reason i couldn't get my head round it. But the ester ketone example you gave clicked something in my head haha. Too late for revision thanks
