Siliaplate tlc

Manufactured by Silicycle
Sourced in Canada

SiliaPlate TLC is a thin-layer chromatography (TLC) plate product offered by Silicycle. It is used for separating and analyzing complex mixtures of chemical compounds. The plate is coated with a uniform layer of silica gel, a common adsorbent material, which provides the stationary phase for TLC.

All chemicals used were purchased from Aldrich (CA) and used without further purification. Purification of compounds was carried out by silica gel circular chromatography (Chromatotron model 7924, Harrison Research) or by flash chromatography. TLC was run on silica gel coated aluminium sheets (SiliaPlate TLC, Silicycle) with detection by UV light (254 nm, UVS-11, Mineralight shortwave UV lamp). Melting points were obtained using a MELTEMP (model 1001D) melting point apparatus. FTIR spectra were recorded on a Nicolet Impact 400 spectrometer. NMR spectra were recorded on a Bruker Avance III 400 MHz spectrometer using TMS as an internal standard. High-resolution mass measurements were performed on a Bruker Daltonics' micrOTOF instrument in positive or negative electrospray.

Synthetic Organic Chemistry Protocol

All of the chemicals
were of reagent grade and were used as purchased. Reactions were monitored
by TLC analysis using 250 μm glass backed silica gel plates
(SiliaPlate TLC, Silicycle, Quebec City, Canada) and compounds were
visualized by UV light (254 and 365 nm). Flash column chromatography
was carried out using either alumina (Aluminum Oxide, neutral, ∼150
mesh, Sigma-Aldrich, St. Louis, MO, USA) or silica gel (SiliaFlashP60,
230–400 mesh, Silicycle, Quebec City, Canada). Both 1H and 13C NMR (300, 500, or 600 MHz) spectra were acquired
using a nondeuterated solvent peak as an internal reference. High-resolution
mass spectra (HRMS) were recorded using electrospray ionization. Rapid
equilibrium dialysis (RED) experiments were performed using a single-use
rapid equilibrium dialysis apparatus equipped with 8K MWCO membranes
(Thermo Scientific Pierce, Rockford, IL, USA; product number 90006).
Compound 14, 1,1′-dioctadecyl-3,3,3′,3′-tetramethylindocarbocyanine
perchlorate, was purchased from Life Technologies (Grand Island, NY,
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.
