NovaSynTG hydroxy resin is a composite of low cross-linked polystyrene and 3000-4000 M.W. polyethylene glycol, in which the ends of the PEG chains have been functionalized with hydroxyl groups. The 130 μm beads have a narrow size distribution, high diffusion rates and excellent swelling across a wide range of solvents from toluene to water [1-3], making them ideally suited to the synthesis of serial and parallel libraries by organic solid phase synthesis.This support has been used for the solid phase immobilization of carboxylic acids [4-9], with cleavage by saponification with dilute aq. NaOH.The product number for this product was previously 01-64-0096.To obtain a certificate of analysis (CoA) of a lot that begins with the letter “A”, please select the option in the right hand menu “Request a COA for Lot#s starting with A”.
