    A common type of organic acid anhydride is a carboxylic anhydride, where the parent acid is a carboxylic acid, the formula of the anhydride being (RC(O)) 2 O. Symmetrical acid anhydrides of this type are named by replacing the word acid in the name of the parent carboxylic acid by the word anhydride.

    Acetic Anhydride - an overview | ScienceDirect Topics

    Acetic anhydride is the only monocarboxylic acid anhydride that is important in modification reactions. The acetylation of the amino groups of proteins can be made relatively specific if the reaction is carried out in saturated sodium acetate, since the O -acetyltyrosine derivative is unstable to an excess of acetate ions ( Fraenkel-Conrat, 1959 ).
