Sigma Aldrich 1,4-Butanediol diglycidyl ether

1,4-Butanediol diglycidyl ether (BDDE) is a viscous liquid , which is hygroscopic in nature. BDDE is the most commonly used homobifunctional epoxide compound. BDDE may react with amines, hydroxyls, sulfhydryl groups to produce secondary amines, ether or thioether bonds respectively.BDDE is a cross linking agent used for preparing amylose, xylan and hydroxyethyl-celluloseto cross link polyethylenimine which also serves as a hole-blocking layer in organic solar cellsto cross link hyaluronic acid into hydrogelsfor the activation of soluble dextran polymers.Amine or hydroxyl containing bis-epoxy supports are reacted with BDDE to form particles containing terminal epoxide group for immobilization reactions.
