SYNTHESIS AND ANTIBACTERIAL SCREENING OF SCHIFF BASES DERIVED FROM 3-(5-BROMOTHIOPHEN-2-YL)-1-(4-CHLOROPHENYL)-1H-PYRAZOLE-4-CARBALDEHYDE
A series of new Schiff bases were synthesized by condensation of 3-(5-bromothiophen-2-yl)-1-(4-chlorophenyl)-1H-pyrazole-4-carbaldehyde with different aromatic aldehydes. The 3-(5-bromothiophen-2-yl)-1-(4-chlorophenyl)-1H-pyrazole-4-carbaldehyde was prepared from 1-(1-(5-bromothiophen-2-yl)ethylidene)-2-(4-chlorophenyl)hydrazine by the Vilsmeier Haack reaction. The 1-(1-(5-bromothiophen-2-yl)ethyl...

STABILITY INDICATING METHOD DEVELOPMENT AND VALIDATION FOR THE ESTIMATION OF ERTUGLIFLOZIN AND METFORMIN IN BULK AND PHARMACEUTICAL DOSAGE FORM BY ULTRA PERFORMANCE LIQUID CHROMATOGRAPHY
A simple, accurate, precise method was developed for the simultaneous estimation of the Ertugliflozin and Metformin in Tablet dosage form. For the method development, Chromatogram was run through HSS C18 (100 × 2.1 mm, 1.7µ) column at a flow rate of 0.3 ml/min. and buffer used in this method was Ortho Phosphoric Acid buffer. The temperature was maintained at 30 °C. The optimized wavelength sele...
