4-(Chloromethyl)pyridine hydrochloride, 98%, Thermo Scientific Chemicals
Description
It finds its application as a reagent for protection of carboxyl termini of peptides as 4-picolyl esters, providing a polar 'handle' which aids in separation and purification of the peptide. The group can be introduced in the presence of a base, e.g. tetramethylguanidine, is stable to acid-catalyzed removal of Cbz protecting group and can be removed by base, Na in liquid ammonia or catalytic hydrogenolysis. It is also applied in conjunction with Amberlyst™15 resin in peptide synthesis. It is an important raw material and intermediate used in organic synthesis, pharmaceuticals and agrochemicals.
