144978-35-8 - Definition and Background:

1-Boc-D-Pyroglutamic Acid Ethyl Ester (Boc-D-Pyr-OEt) (CAS: 144978-35-8) is a synthetic amino acid derivative that has a Boc (tert-butyloxycarbonyl) group attached to the α-amino group and an ethyl ester group attached to the carboxyl group of pyroglutamic acid. The Boc group, which is commonly used to protect amine groups in organic synthesis, can be removed by acid treatment, allowing access to the primary amine for further reaction.
