In
addition to the structure shown above, there is a water molecule associated
with the compound, leading to its IUPAC name being cefprozil monohydrate., or
(6R,7S) 7[(R) - 2 amino-2(p hydroxyphenyl) acetamido]-8-oxo-3-propyl-5-thia-1-azabicyclo
[4.2.0]oct-2-ene-2-carboxylic acid monohydrate. Thus the empirical formula is
more accurately represented as C18H19N3O5S.H2O
