1,2-NAPHTHOQUINONE-4-SULFONIC ACID SODIUM SALT Usage And Synthesis

Chemical Properties	powder
Uses	1,2-Naphthoquinone-4-sulfonic acid sodium salt is used in the characterization of phanerochaete chrysosporium. Used in the synthesis of carbohydrate based napthoquinones as anticancer agents.
Uses	Colorimetric determination of amino acids and amines.
Uses	Colorimetric determination of amino acids and amines1,2-Naphthoquinone-4-sulfonic acid sodium salt is used for the colorimetric determination of amino acids, amines and procaine hydrochloride in pharmaceutical preparations. It is also used in the characterization of phanerochaete chrysosporium. Further, it acts as an intermediate in the synthesis of carbohydrate based napthoquinones, which acts as anticancer agents.
Purification Methods	It forms yellow crystals from aqueous EtOH and should be dried at 80o in vacuo. Its solubility in H2O is 5% [Martin & Fieser Org Synth Coll Vol III 633 1955, Danielson J Biol Chem 101 507 1933, UV: Rosenblatt et al. Anal Chem 27 1290 1955]. [Beilstein 11 IV 668.]
