Synthesis and Characterization of Novel Compounds

Check if the same lab product or an alternative is used in the 5 most similar protocols
Chemicals and solvents were obtained from Sigma Aldrich (St. Louis, MO, USA) with the exception of resorcinol and 4-bromophenylacetic acid (Acros Organic, Carlsbad,CA, USA), 1,4-dibromobutane (Oakwood Chemical, Estill, SC, USA), sodium iodide (Fisher Scientific, Waltham, MA, USA), and N,N,N’-trimethyl-1,2-ethylenediamine (Toyko Chemical, Tokyo, Japan). Nuclear magnetic resonance spectra were determined in DMSO-d6 using Varian instruments (1H, 400; 13C, 100Mz; Varian, Inc., Palo Alto, CA, USA). High resolution electrospray ionization (ESI) mass spectra were recorded on a LTQ-Orbitrap Velos mass spectrometer (Thermo Fisher Scientific, Waltham, MA, USA). The FT resolution was set at 100,000 (at 400 m/z). Samples were introduced through direct infusion using a syringe pump with a flow rate of 5 μL/min. Purity was established by combustion analyses performed by Atlantic Microlabs, Inc. (Norcross, GA, 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.
