Aldrich provides a wide range of solvents with extremely low residual water, excellent chemical purity, and the highest isotopic enrichment available. The highest deuterium enrichment solvents are available exclusively from Aldrich. We are alone in offering 13C-depleted solvents, useful when identifying signals of interest located in the same region of the spectrum as the 13C solvent's peaks. Aldrich now offers a complete line of NMR Reference Standards, which are fully tested to assure that the samples meet all NMR performance requirements. In addition to solvents Aldrich/Isotec offers a wide variety of compounds for NMR studies. These include 13C labeled glucose and 15N enriched ammonium salts for protein synthesis, a wide variety of compounds labeled with NMR active nuclei, and custom synthesis of unique compounds. |
