Calconcarboxylic acid Usage And Synthesis
Chemical Propertiesdark violet powder
UsesCalconcarboxylic acid is used as an indicator for calcium titrations with ethylenediaminetetraacetic acid (EDTA) in the presence of magnesium.
Purification MethodsPurify it via its p-toluidinium salt, viz: dissolve the dye in warm 20% aqueous MeOH, treat with an equivalent of p-toluidine and cool to precipitate the salt. Finally recrystallise the acid from hot water. [Itoh & Ueno Analyst (London) 95 583 1970.] It is an indicator and complexes with Ca2+ in presence of Mg2+ and other metal ions [Patton & Reeder Anal Chem 28 1026 1956, Prentoe & Prentoe Analyst 106 227 1981].
