H2N-PEG2-Propyne Chemical Properties,Uses,Production
Description
Propargyl-PEG2-amine is a crosslinker that is reactive with NHS esters, carbonyls (carboxylic acid, ketone, aldehyde). The propargyl group can participate in copper catalyzed azide-alkyne Click Chemistry reaction to form a stable triazole linkage.
Uses
2-[2-(2-Propynyloxy)ethoxy]ethylamine is used in preparation of RSV F protein inhibitors conjugated to Fc variants and albumins.
Synthesis
1245006-63-6
944561-44-8
The general procedure for the synthesis of 2-(2-(prop-2-yn-1-yloxy)ethoxy)ethylamine from the compound (CAS:1245006-63-6) is as follows: General method: polymer-loaded triphenylphosphine (1.15 eq.) was added to an anhydrous tetrahydrofuran (THF) solution of azide alkynes S3. Subsequently, the reaction mixture was stirred at room temperature for 48 hours. Next, deionized water (1 mL) was added to the flask and the resulting mixture was continued to be stirred at room temperature for 48 hours. Upon completion of the reaction, the mixture was filtered through a bed of diatomaceous earth to collect insoluble solids and washed with ethyl acetate (25 mL). Finally, the combined filtrates were concentrated under reduced pressure to give the target product aminoalkynes 6.
