All melting points (MPs) were measured on an Electrothermal Gallenkamp apparatus (Weiss Technik, London, UK). Infrared (IR) spectra were recorded in potassium bromide disks on SP3300 (Pye Unicam, Cambridge, England) and 8101 PC (Shimadzu, Tokyo, Japan) IR spectrophotometers. 1H nuclear magnetic resonance (NMR) and 13C NMR spectra were recorded on a Varian Mercury VXR-300 spectrometer (300 MHz). Mass spectra were recorded on Shimadzu GCMS-Q1000-EX and GCMS 5988-A HP spectrometers, and ionizing voltage was 70 eV. Elemental analyses were carried out at the Microanalytical Center of Cairo University, Giza, Egypt. Biological evaluation of the products was carried out in the Microbiology Division of the Microanalytical Center of Cairo University.

An electrothermal Gallenkamp apparatus was operated to measure the melting points for the newly synthesized compounds. A Pye-Unicam SP300 instrument in potassium bromide discs was used to measure IR spectra. A Varian Mercury VXR-300 spectrometer (300 MHz for 1H-NMR and 75 MHz for 13C-NMR) was manipulated to measure the 1H-NMR and 13C-NMR spectra, and the chemical shifts were related to those of the solvent. GCMS-Q1000-EX Shimadzu and GCMS 5988-A HP spectrometers were used to record the mass spectra of the samples at an ionizing voltage of 70 eV. Elemental analyses were carried out at the Microanalytical Centre of Cairo University, Giza, Egypt.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
