The complexation reaction involved stirring ethanolic solutions of Zn(II), Cu(II), Ni(II), or Zr(IV) salts with a Schiff base ligand. <br />Thermal decomposition of Zn(II), Cu(II), Ni(II), and Zr(IV) complexes was analyzed under nitrogen, heating at 30 °C/min, measuring weight loss from ambient temperature to 800 °C. The antibacterial activity, antioxidant properties, and cytotoxicity of the synthesized compounds wereexamined using reported methods.</p> <p><strong>Results: </strong>Cu(II), Zn(II), Ni(II), and Zr(IV) complexes with a Schiff base ligand were synthesized. Analyzed through Fourier-transform infrared spectroscopy (FTIR), Ultraviolet-visible (UV-vis) and physiochemical tests and confirmed the structures. Magnetic susceptibility and electronic spectra suggested geometries, supported by thermogravimetric data. Antibacterial tests revealed complexes had higher activity than ligands, and also showed antioxidant properties.</p> <p><strong>Conclusion: </strong>Cu(II), Zn(II), Ni(II), and Zr(IV) Schiff base complexes were synthesized, showing tetrahedral or square planar geometries. They exhibited thermal stability and strong antibacterial activity, outperforming the ligand alone.</p> SAJIB HOSSAIN ASHRAFUL ISLAM FARIA TASNIM FARUK HOSSEN KUDRAT E-ZAHAN ALI ASRAF Copyright (c) 2024 SAJIB HOSSAIN, ASHRAFUL ISLAM, FARIA TASNIM, FARUK HOSSEN, KUDRAT E-ZAHAN, ALI ASRAF https://creativecommons.org/licenses/by-nc/4.0 2024-10-01 2024-10-01 1 11 10.22159/ijcr.2024v8i4.231 THE INDUSTRIAL IMPORTANCE OF TECHNOLOGY TRANSFER FOR ANALYTICAL METHOD DEVELOPMENT AND VALIDATION–APPLICATION TO VILAZODONE HYDROCHLORIDE DOSAGE FORM https://ijcr.info/index.php/journal/article/view/235 <p><strong>Objective: </strong>The research aims to create a fast, economical, and efficient tech transfer method for analyzing bulk materials and pharmaceutical dosage forms.</p> <p><strong>Methods: </strong>The analysis was performed using an Acquity UPLC BEH C18 analytical column (130 Å, 1.7 µm, 3 mm x 100 mm) with detection of the analyte at 238 nm. The mobile phase flow rate was optimized at 0.3 ml/min, and an injection volume of 0.5 µl** was used. The isocratic mobile phase consisted of a blend of buffer (0.1% OPA) and acetonitrile at a ratio of 40:60% v/v.</p> <p><strong>Results: </strong>All validation parameters of the analytical method were acceptable. The analyte eluted at 3.08 min with satisfactory theoretical plates and a tailing factor. The recovery of the analyte was 99-100%, and the method's precision was 0.59 and 0.72% RSD. The technique showed no interference, indicating specificity. The linearity was demonstrated over the 20-60 µg/ml range, with a regression coefficient of 0.999.</p> <p><strong>Conclusion: </strong>The developed method is cost-effective, specific with minimal interference, and time-saving. It also reduces solvent consumption for quality control analysis of vilazodone hydrochloride samples. The method demonstrates good linearity, robustness, and accuracy.</p> PULAGURTHA BHASKARARAO MATTA SARIKA CHITRA LAKSHMI MADHAVI MOHAN GUPTA KOLLIPARA GUNTUR PRASHANTHI Copyright (c) 2024 PULAGURTHA BHASKARARAO, MATTA SARIKA, CHITRA LAKSHMI MADHAVI, MOHAN GUPTA KOLLIPARA, GUNTUR PRASHANTHI https://creativecommons.org/licenses/by-nc/4.0 2024-10-01 2024-10-01 12 17 10.22159/ijcr.2024v8i4.235
