Chemical Information
FooDB NameCatechol 1-O-sulphate
DescriptionPyrocatechol sulfate, also known as 1,2-benzenediol mono(hydrogen sulfate) or (2-hydroxyphenyl) hydrogen sulfate, is a member of the class of compounds known as phenylsulfates. Phenylsulfates are compounds containing a sulfuric acid group conjugated to a phenyl group. Pyrocatechol sulfate is slightly soluble (in water) and an extremely strong acidic compound (based on its pKa). Pyrocatechol sulfate can be found primarily in blood.
