The IR spectra were recorded using a PerkinElmer FTS FT-IR spectrometer and SHIMADSU spectrophotometer. UV-spectra has been recorded with a PerkinElmer or Varian Cary 5000 UV-vis NIR spectrophotometer. The melting point was determined using a Gallenkamp melting point apparatus. The NMR spectra were recorded using a 400 MHz Bruker AM400 spectrometer and 400 MHz Bruker FTNMR Ultra Shield with tetramethylsilane as the internal standard. HRESIMS mass spectra measured on a Bruker micro TOF mass spectrometer. Quick column chromatography (QCC) and column chromatography (CC) were carried out on silica gel 60 (5–40 μm, SiliCycle® Inc.) and silica gel 100 (63–200 μm, SiliCycle® Inc.), respectively. Sephadex LH-20, when indicated, was also used for CC. Precoated thin-layer chromatography (TLC) was performed using silica gel 60 F254 plates (Merck, USA).
Silica gel 100
Manufactured by Silicycle
Sourced in Canada
Silica gel 100 is an inorganic, amorphous form of silicon dioxide. It is a highly porous material with a large surface area, making it useful as an adsorbent and desiccant. Silica gel 100 has a particle size range of 100-200 mesh and is commonly used in various applications where adsorption or drying is required.

Melting points were measured with a Büchi B-540 melting point apparatus (Flawil, Sankt Gallen, Switzerland). UV–vis spectra were recorded with a Varian Cary 5000 UV–vis–NIR spectrophotometer (Agilent Technologies, Santa Clara, CA, USA). The IR spectra were recorded using a Perkin-Elmer FTS FT-IR spectrophotometer (Waltham, MA, USA). The NMR spectra were measured using 400, 500, or 600 MHz Bruker spectrometers (Billerica, MA, USA). HRESITOFMS and LRESIMS spectra were carried out on a Bruker-Hewlett-Packard 1100 Esquire-LC system mass spectrometer (Billerica, MA, USA) and Waters 2695 HPLC (Milford, MA, USA), Waters ZQ equipped with ESCI ion source mass spectrometer, respectively. All quick column chromatography (QCC) and column chromatography (CC) were carried out on silica gel 60 (5–40 μm, SiliCycle Inc., Québec, QC G1P 4S6, Canada) and silica gel 100 (63–200 μm, SiliCycle Inc.), respectively. Sephadex LH-20, when indicated, was also used for CC. Precoated thin-layer chromatography (TLC) plates of silica gel 60 F254 were used for analytical purposes.
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.
