General description

4-Nitrocatechol sulfate is an aromatic sulfate.

Application

4-Nitrocatechol sulfate dipotassium salt has been used as a substrate in mucopolysaccharidoses VI (MPS VI) analysis. It has also been used to measure the activity of glycosaminoglycan (GAG)-degrading enzymes-arylsulfatase B, and exoglycosidases.

Substrates

Chromogenic sulfatase substrate.

Lysosomes of trypanosomatid protozoa are poorly known. In this work we have cytochemically detected the lysosomal enzyme aryl sulphatase in the trypanosomatids Trypanosoma cruzi and Crithidia fasciculata, by using p-nitrocatecholsulphate as substrate. Positive reaction was located exclusively inside membrane-bound cytoplasmic
