2-Aminobenzyl Alcohol

Sigma-Aldrich Supelco

2-Aminobenzyl alcohol is oxidatively cyclized with an array of ketones in dioxane at 80°C in the presence of a ruthenium catalyst and KOH to give corresponding quinolines. It undergoes oxidation catalyzed by heterotrimetallic RuMnMn species on the hydrotalcite surface in the presence of O2 to yield 2-aminobenzaldehyde

TLC Silica gel 60

Sigma-Aldrich Supelco

Our classical silica TLC plates are based on a combination of our proven silica gel 60 and the addition of a unique polymeric binder resulting in a very adherent and hard surface that will not crack or blister and even allow writing with a pensil on the surface without risk to damage the layer.

Methanol for HPLC, ≥99.9%

Sigma-Aldrich Supelco

Methanol is an organic solvent that can be synthesized from syngas in the presence of CuO/ZnO/Al2O3 catalysts. It is an ideal candidate as a hydrogen source in fuel cell technology due to its high H/C ratio, low propensity for soot generation, relatively low reforming temperature and as it exists in liquid state at room temperature. In a direct methanol fuel cell (DMFC), methanol undergoes oxidation with air to generate electr…

Discovery® BIO Wide Pore C18 HPLC Column

Sigma-Aldrich Supelco

Peptide maps generated by RP-HPLC provide valuable information about protein structure, stability, and purity. To be effective, the RP-HPLC column must be able to resolve a high percentage of the peptides in the sample. The more peptides, the better the information. Discovery BIO Wide Pore C18 gives unsurpassed RP-HPLC resolution of peptide maps from enzymatic digests. The improvements in silica and bonded-phase chemistry we h…
