TCI C0683 N-Ethoxycarbonylphthalimide (CAS 22509-74-6) is a reagent for introducing the phthaloyl protecting group onto primary amines under mild conditions. It is widely used in peptide synthesis and amino acid chemistry, where selective amino protection is essential before coupling steps. Compared with harsher classical methods, it is better suited to substrates bearing sensitive functional groups. This TCI grade is designated for peptide synthesis and is offered in 25 g, 100 g, and 500 g pack sizes.
