Allgemeine Beschreibung

Reinecke salt [ammonium tetrarhodanatodiamminechromate(III)] is an ammonium salt. It participates in the quantitative precipitation of histones as well as basic compounds present in an acid tissue extract by forming reineckate complexes.

Anwendung

Farbreagens und Fällungsmittel für Quecksilber. Fällungsmittel für primäre und sekundäre Amine und bestimmte Aminosäuren.
Reinecke salt may be used as a precipitation reagent for the isolation of quaternary ammonium alkaloids (QAAs) in the dried powder of Rhizoma Corydalis. Quantitative analysis of these QAAs was conducted by MALDI-MS (Matrix-Assisted Laser Desorption Ionization - Mass Spectrometry). It may be used for the fabrication of bulk Meldola blue-zirconium phosphate-Reinecke salt screen-printed electrodes (bMBZrPRs-SPEs).

Three accurate, rapid and simple atomic absorption spectrometric, conductometric and colorimetric methods were developed for the determination of norfloxacin (NRF), ciprofloxacin (CIP), ofloxacin (OFL) and enrofloxacin (ENF). The proposed methods depend upon the reaction of ammonium reineckate with the studied
