Chemical shift (δ) was expressed as in parts per million (ppm) and the coupling constant (J) was reported in Hertz (Hz). These products were characterized by HRMS (Micromass® LCT Premier XE, currently merged to Waters Technologies) (positive mode, electrospray + ionization (ESI)).
1600 series ftir spectrophotometer
The 1600 Series FTIR Spectrophotometer is a compact and versatile instrument designed for infrared spectroscopy analysis. It utilizes Fourier Transform Infrared (FTIR) technology to provide high-resolution, accurate, and reproducible measurements of a wide range of samples.

Characterization of Organic Compounds by Spectroscopy
Chemical shift (δ) was expressed as in parts per million (ppm) and the coupling constant (J) was reported in Hertz (Hz). These products were characterized by HRMS (Micromass® LCT Premier XE, currently merged to Waters Technologies) (positive mode, electrospray + ionization (ESI)).
General Organic Reaction Protocols
were carried out in oven-dried glassware. The chemicals and solvents
were purchased from Sigma-Aldrich, Spectrochem, or Acros and were
used without any purification except THF (tetrahydrofuran), which
was dried by refluxing over sodium followed by distillation. Reactions
were monitored by TLC, which are precoated by silica gel (Kieselgel
60F 254, Merck), and the spots were detected under UV light (254 nm).
Compounds were purified by column chromatography using silica gel
(particle size 100–200 mesh). 1H and 13C NMR spectra were characterized in CDCl3 or DMSO-d6 solution by using (Wormhole-vnmrs/Bruker/Jeol-Delta/Varian)
400/300 MHz spectrophotometers. Chemical shifts are reported as ppm
(δ) relative to TMS (δ 0.0) as the internal standard. 1H NMR data is recorded as follows: chemical shift [multiplicity,
coupling constant(s) J (Hz), relative integral] where
multiplicity is defined as s (singlet), d (doublet), t (triplet),
q (quartet), m (multiplet), and bs (broad singlet). Mass spectra were
recorded on a 6430 Triple quardrupole mass spectrometer for ESI and
are given in m/z. FTIR spectra were
recorded on a PerkinElmer 1600 series FTIR spectrophotometer. UV spectra
were recorded on a PerkinElmer Lambda 25 UV–visible spectrophotometer
(USA).

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.
