General description

The degradation and adsorption of 1-diazo-2-naphthol-4-sulfonic acid was studied using sewage sludge derived porous carbon.

Application

Involved in studies to analyze structure-activity relationships to predict biodegradability of N-heterocycles in wastewater and polluted soil

Reactant used as hydrazinonaphthalene and azonaphthalene thrombopoietin mimics acting as nonpeptidyl promoters of megakaryocytopoiesis
