Glacial acetic acid is used in analytical chemistry for the estimation of weakly alkaline substances such as organic amides. Glacial acetic acid is a much weaker base than water, so the amide behaves as a strong base in this medium. It then can be titrated using a solution in glacial acetic acid of a very strong acid, such as perchloric acid. [52]

It is prepared by a mixing saturated solution of picric acid in 95% ethanol (80ml) with formalin (37-40% formaldehyde) (15 ml) and glacial acetic acid (5ml). [8] Gendre's fixative contains more picric acid than Bouin's, because of greater solubility (6.23%w/v) in ethanol than in water (1.23%w/v).
Acetic anhydride, or ethanoic anhydride, is the chemical compound with the formula (CH 3 CO) 2 O.Commonly abbreviated Ac 2 O, it is the simplest isolable anhydride of a carboxylic acid and is widely used as a reagent in organic synthesis.
Carnoy's solution is a fixative composed of 60% ethanol, 30% chloroform and 10% glacial acetic acid, 1 gram of ferric chloride. [1] [2]Carnoy's solution is also the name of a different fixation composed of ethanol and glacial acetic acid (3:1).
