Potentiometric studies of binary complexes of bivalent metal ions with 3, 5 dinitrosalicylic acid


ABSTRACT:

The binary complexes of metal ions Fe+3,Co2+,Ni2+,Cu2+,Zn2+,Cd2+ with 3,5 Dinitrosalicylic acid as a ligand were studied in aqueous media using Irving Rosotti method. Acidity constant and stability constant were studied at 270C at ionic strength 1N NaNo3. Stability constants calculated by half integral method and point wise method were compared and found to follow Irving and Williams rule.

A Validated specific Stability-indicating RP-HPLC method for Aripiprazole and its related substances

Image
ABSTRACT : A validated specific stability indicating reversed-phase liquid chromatographic method was developed for the quantitative determination of Aripiprazole and its related substances in bulk samples, pharmaceutical dosage forms in presence of degradation products. Forced degradation studies were performed on bulk sample of Aripiprazole as per ICH prescribed stress conditions using acid, base, oxidative, thermal stress and photolytic degradation to show the stability indicating power of the method. Significant degradation was observed during basic stress and no degradation was observed in other stress conditions. The chromatographic method was optimized using the samples generated from forced degradation studies and the impurity spiked with Aripiprazole. Good resolution between the peaks corresponds to impuritiy-1, degradation products from the analyte were achieved on YMC PACK C18 column using the mobile phase consists a mixture of Sodium dihydrogen Orthophosphate dehydra...
