Synthesis and electrochemical studies of NaCoPO as an efficient cathode material using natural deep eutectic solvents for aqueous rechargeable sodium-ion batteries.

In this work, sodium cobalt phosphate (NaCoPO) was successfully prepared by a cost-effective ionothermal method using a deep eutectic solvent (DES) for the first time. The synthesized NaCoPO was used to fabricate a cathode material for aqueous rechargeable sodium-ion batteries. The surface morphology of the prepared materials and its compositional analysis were done by using field emission scanning electron microscopy (FESEM) and energy-dispersive X-ray (EDX) analysis, respectively.

Development of a Stability-Indicating Purity Method for Ubrogepant Through Stress Degradation Analysis, Extraction, and Characterization of Unidentified Degradation Products Using Flash Chromatography, NMR, IR, and LC-MS.

Background: Ubrogepant is a prescription medication used to prevent migraine headaches. It is currently available in tablet form.

Objective: The goal of this work is to investigate the drug degradation profile of ubrogepant, as well as to isolate and characterize undiscovered ubrogepant degradation products by utilizing LC-MS, NMR, and IR spectroscopic analytical techniques and, furthermore, to develop a high-resolution, sensitive, stability-indicating analytical approach for detecting and quantifying ubrogepant degradation products in its pharmaceutical formulation.
