All reagents were purchased from Aldrich and were used as received. All solvents were dried before use. 1H NMR (300.13185 MHz) and 13C NMR (75.47564 MHz) analyses in CDCl3 were performed on a Bruker 300 MHz spectrometer, using TMS as the internal reference. Chemical shifts (δ) are reported in p.p.m. IR spectra were recorded on a Perkin–Elmer FT–IR 1600 spectrophotometer in the 4000–400 cm−1 range. Elemental analyses were performed in a Thermofinniga Flash 112 instrument under standard conditions.
Ft ir 1600 spectrophotometer
Manufactured by PerkinElmer
Sourced in United States
The FT–IR 1600 spectrophotometer is an analytical instrument designed to measure the absorption or transmission of infrared radiation by a sample. It functions by shining a beam of infrared light through a sample and detecting the amount of light that is absorbed or transmitted at different wavelengths. This information can be used to identify and quantify the chemical composition of the sample.

GSH and amino acid derivatives were purchased from Sigma-Aldrich (St. Louis, MO) and Bachem (Bubendorf, Switzerland). All other chemicals and solvents were of analytical grade and were supplied from Sigma-Aldrich and VWR (Radnor, PA). All the reactions were monitored by analytical TLC on Merck (Kenilworth, NJ) 60 F 254 plates developed with the following solvents: (a) n-BuOH/AcOH/H 2 O (2:1:1); (b) CHCl 3 /MeOH (99:1); (c) CHCl 3 /MeOH (98:2). Column chromatography was carried out in absorption using Merck 60 silica gel (230-400 mesh). Melting points were determined on a Bu ¨chi B-450 apparatus (Uster, Switzerland) and are uncorrected. Elemental analyses (C, H, N and S) were performed on a Carlo Erba 1106 Analyzer (Milano, Italy) and were within ±0.4% of the theoretical values. IR spectra were recorded employing a Perkin-Elmer FTIR 1600 spectrophotometer (Waltham, MA). 1 H (300 MHz) and 13 C (75.43 MHz) NMR spectra were acquired on a Varian VXR-300 instrument (Palo Alto, CA). Chemical shifts are reported in ppm, referenced to residual solvent peaks and multiplicities are indicated as s (singlet), d (doublet), t (triplet), m (multiplet) and br (broad). Peak assignments were confirmed by 2D 1 H-13 C hetero-correlated experiments.
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.
