Application

Reinecke salt can be used as a precipitation reagent for the precipitation of basic compounds such as amines, amino acids, and alkaloids as their reineckate complexes. It is also used in the spectrophotometric determination of promazine along with alizarin S by the formation of the promazine ion-association complex.

Three accurate, rapid and simple atomic absorption spectrometric (AAS), conductometric and colorimetric methods were developed for the determination of gatifloxacin (GTF), moxifloxacin (MXF) and sparfloxacin (SPF). The proposed methods depend upon the reaction of ammonium reineckate with the studied drugs

An automatic method for the determination of amylocaine and bromhexine hydrochloride by atomic absorption spectrometry (AAS) is proposed. The drugs were determined indirectly by formation of reineckates, extraction into 1,2-dichloroethane and measurement of chromium in the organic phase. The chemical
