Phosphate titration reinecke salt
WebReinecke 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. Webreplaces the labor-intensive steps required for reaction and precipitation of the reinecke salt complex and spectrophotometric measurement. The -MS/MS assay precision was 7HPLC% (relative standard deviation) and the overall mean spiking recovery was 100% across four sample matrices.
