2-[2-(叔丁氧羰基氨基)乙氧基]乙氧基乙酸二环己胺盐 (CAS No.560088-79-1)

Product Name:2-[2-(tert-Butoxycarbonylamino)ethoxy]ethoxyacetic acid dicyclohexylamine salt

English Name:2-[2-(tert-Butoxycarbonylamino)ethoxy]ethoxyacetic acid dicyclohexylamine salt

CAS No.:560088-79-1

Aliases:Boc-NH-PEG2-acetic acid DCHA salt, Boc-NH-PEG2-COOH dicyclohexylamine salt, Dicyclohexylammonium 2-[2-[2-(tert-butoxycarbonylamino)ethoxy]ethoxy]acetate

Molecular Formula:C23H44N2O6

Physical Properties:White to off-white crystalline powder. Soluble in organic solvents such as dichloromethane, methanol and DMF; slightly soluble in water. Sensitive to light and heat; store sealed and protected from light at low temperature. Contains both Boc-protected amino and carboxyl groups; the Boc group can be removed under acidic conditions.

Uses:Used as a fine chemical and pharmaceutical intermediate, commonly employed in peptide synthesis, PEGylation modification, and construction of linkers for ADC/PROTAC drug development. The dicyclohexylamine salt form facilitates storage and purification of the carboxylic acid; the free acid can be released for amidation or esterification reactions.
