  • Formula:C18H13ClNNa2O5P
  • Molecular Weight:435.71

IUPAC Name: sodium 3-((4-chloro-2-methylphenyl)carbamoyl)naphthalen-2-yl phosphate

InChIKey: TYCHZTPSWMGRRI-UHFFFAOYSA-L

SMILES: O=C(C1=C(OP(O[Na])(O[Na])=O)C=C2C=CC=CC2=C1)NC3=CC=C(Cl)C=C3C

Biological Activity: Naphthol AS-TR phosphate disodium is a substrate for alkaline phosphatase and acid phosphatase. Naphthol AS-TR phosphate disodium enables histochemical enzyme localization in bone sections. Naphthol AS-TR phosphate disodium is hydrolyzed to release insoluble naphthol AS-TR, which couples with diazonium salts to form a locally deposited azo dye, used for histochemical staining of paraffin-embedded tissues and for localization in freeze-dried tissues.
