Silica gel 40 60 μm

Manufactured by Agela Technologies

Silica gel (40-60 μm) is a form of porous, granular material composed of silicon dioxide. It is characterized by a particle size range of 40-60 micrometers. The primary function of this product is to act as a desiccant, possessing the ability to adsorb moisture and maintain a dry environment.

Example 1

General Synthetic Procedure: All commercial reagents were purchased and used as received without further purification. Pd(OAc)₂was purchased from Pressure Chemical Co. n-Bu₄NBr, CuI, 2-(tributylstannyl)pyridine and 2-picolinic acid were purchased from Sigma Aldrich. Silica gel (40-60 μm) was purchased from Agela Technologies and BDH. DMSO, toluene (low water), and acetic acid were purchased from Alfa Aesar, J. T. Baker, Fluke and BDH respectively.

All reactions were carried out under an inert N₂atmosphere in oven-dried glassware. External bath temperatures were used to record all reaction temperatures. Flash column chromatography was carried out with silica gel. Proton and carbon NMR spectra (¹H NMR and ¹³C NMR) were recorded in dimethyl sulfoxide-d₆(DMSO-d₆) on a Varian 400 MHz NMR spectrometer. The solvent residual peak (DMSO-d₆) was calibrated to 2.50 ppm for ¹H NMR and 39.52 ppm for ¹³C NMR. Multiplicities are abbreviated as follows: s=singlet, d=doublet, dd=doublet of doublets, t=triplet, br=broad, m=multiplet.

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.
