English description（英文原文，共 1257 字符）
Product Name:Bromo-PEG3-t-butyl ester
English Name:Bromo-PEG3-t-butyl ester
CAS No.:782475-37-0
Aliases:Mono-bromo triethylene glycol t-butyl propionate, Bromo-PEG3 tert-butyl ester, Bromo-PEG3 propionic acid t-butyl ester
Molecular Formula:C13H25BrO5
Physical Properties:A colorless to pale-yellow transparent liquid or low-melting solid at room temperature. Readily soluble in dichloromethane, chloroform, DMF, DMSO and other organic solvents; slightly soluble in water. Hygroscopic to some extent, recommend storage under dry inert gas protection.
Uses:This product is a PEG derivative containing a bromine terminal group and a tert-butyl ester terminal group, used as a linker or modifier in bioconjugation, drug delivery systems, and surface functionalization of materials. The bromine end can undergo substitution reactions with nucleophilic groups such as amino or thiol groups for PEGylation modification, and the tert-butyl ester can be deprotected under acidic conditions to generate a free carboxyl group for subsequent amide coupling.
Technical Specifications:
Purity ≥95% (HPLC)
Molecular weight 341.24
Appearance: colorless to pale-yellow liquid or viscous substance
Storage: 2~8°C, protected from light, sealed
Water content ≤0.5%
