Product Name:Diantipyrylmethane
English Name:Diantipyrylmethane
CAS No.:1251-85-0
Aliases:4,4'-Methylenediantipyrine, 4,4'-Methylenebis(1,5-dimethyl-2-phenyl-1,2-dihydro-3H-pyrazol-3-one)
Molecular Formula:C23H24N4O2·H2O
Physical Properties:White crystalline powder. Stable as solid and in solution. Insoluble in water, ether and alkalis; soluble in acids, ethanol and chloroform. Forms yellow complexes with MoO, UO and Ti4+; forms ion-association complexes with anions or complex anions such as Cl- and IrX, which are readily extracted by organic solvents such as chloroform or carbon tetrachloride.
Uses:Used as a sensitive chromogenic reagent for the spectrophotometric and extraction-photometric determination of iridium, platinum, rhenium, titanium, bismuth, zinc, cobalt, iron, osmium, rhodium, thallium, tungsten and other elements. Used as a precipitant for silicon in gravimetric analysis. Also used as an extractant for various ions and as an intermediate in organic synthesis.
Technical Specifications:
Purity ≥98% (analytical grade)
Melting point: 156-157°C
Solubility: insoluble in water, ether and alkalis; soluble in acids, ethanol and chloroform
Stability: stable as solid and in solution
Forms yellow complexes with MoO, UO and Ti4+
