Anwendungen & Verwendung
Beschreibung
Das Dinatriumsalz der R-Säure bildet farblose, in Wasser leicht lösliche Nadeln. Die Lösung der Salze fluoreszieren meist blau. Die Säure und ihre Salze kuppeln sehr leicht mit Diazoniumsalzen. Das Dinatriumsalz wird daher zur Herstellung einer sehr große
Verwenden
3-Hydroxynaphthalene-2,7-disulfonic Acid Disodium Salt, is used in analytical studies for detecting organic explosives and propellants by fast liquid chromatography quadrupole time-of-flight mass spectrometry.
