  • Miscellaneous
    • Chemical Class:

      An aryl sulfate that is 4-nitrocatechol in which the hydroxy group that is <ital>meta</ital> to the nitro group has been converted to the corresponding hydrogen sulfate. It is used (commonly as its di potassium salt) as a chromogenic substrate for sulphatase. ChEBI CHEBI:41733
