EDC-mediated couplings of Polyester-8-hydroxyl-1-carboxyl bis-MPA dendron

Product Description

Theoretical MW: 830.82 g/mol
Average Molecular Formula: C35H58O22
Number of hydroxyl groups: 8
Number of carboxylic acid groups: 1

This monodisperse compound has multiple surface hydroxyl groups and a single carboxylic acid focal point function. The carboxylic acid function is well suited for EDC-mediated coupling to amine-containing reagents. The hydroxyl groups are selectively reactive with anhydrides or acyl halides (see Figure 1). It is transparent to light in the UV/Vis wavelength region.
