Supramolecular-gel Gelators for Recrystallization and Polymorph Control
Composed of two nitrophenylurea moieties via a carbon tether moiety, our compounds [M3072] and [H1655], are utilized as supramolecular gelators. When a small amount of the gelator is dissolved in organic solvents, it prodcues robust gels while simultaneously binding with dissolved compounds. Supramolecular gel-phase crystallization offers an extremely versatile new tool in pharmaceutical polymorph screening.
Amino acids and their N-protected derivatives, such as Boc- and Fmoc-amino acids, are essential for peptide synthesis. In addition to our new products [B5887], [C3382], and [F1193], click below to see TCI's full selection of reagents for peptide synthesis.
Weinreb and Nahm published in 1981 a very useful method for the ketone synthesis. N-methoxy-N-methylamides, now popularly called Weinreb amides can be used for the synthesis of ketones with organolithium and Grignard reagents. TCI offers a variety of Weinreb amides like [M0919] or [T3326] for clean and effective ketone synthesis.
