text: Esters can also be derived from inorganic acids.
  *Perchloric acid forms perchlorate esters, e.g., methyl perchlorate ()
  *Sulfuric acid forms sulfate esters, e.g., dimethyl sulfate () and methyl bisulfate ()
  *Nitric acid forms nitrate esters, e.g. methyl nitrate () and nitroglycerin ()
  *Phosphoric acid forms phosphate esters, e.g. triphenyl phosphate () and methyl dihydrogen phosphate ()
  *Carbonic acid forms carbonate esters, e.g. dimethyl carbonate () and 5-membered cyclic ethylene carbonate () (if one classifies carbonic acid as an inorganic compound)
  *Trithiocarbonic acid forms trithiocarbonate esters, e.g. dimethyl trithiocarbonate () (if one classifies trithiocarbonic acid as an inorganic compound)
  *Chloroformic acid forms chloroformate esters, e.g. methyl chloroformate () (if one classifies chloroformic acid as an inorganic compound)
  *Boric acid forms borate esters , e.g. trimethyl borate ()
  *Chromic acid forms di-tert-butyl chromate ()
  Inorganic acids that exist as tautomers form two or more types of esters.
  *Thiosulfuric acid forms two types of thiosulfate esters, e.g. O,O-dimethyl thiosulfate () and O,S-dimethyl thiosulfate ()
  *Thiocyanic acid forms thiocyanate esters, e.g. methyl thiocyanate () (if one classifies thiocyanic acid as an inorganic compound), but forms isothiocyanate "esters" as well, e.g. methyl isothiocyanate (), although organyl isothiocyanates are not clasified as esters by the IUPAC
  *Phosphorous acid forms two types of esters: phosphite esters, e.g. triethyl phosphite (), and phosphonate esters, e.g. diethyl phosphonate ()
  Some inorganic acids that are unstable or elusive form stable esters.
  *Sulfurous acid, which is unstable, forms stable dimethyl sulfite ()
  In principle, a part of metal and metalloid alkoxides, of which many hundreds are known, could be classified as esters of the corresponding acids (e.g. aluminium triethoxide () could be classified as an ester of aluminic acid which is aluminium hydroxide, tetraethyl orthosilicate () could be classified as an ester of orthosilicic acid, and titanium ethoxide () could be classified as an ester of orthotitanic acid).
