Abstract
Enantiomers of butanediol diglycidyl ether (BDDE) are present in an enantiomerically enriched enantioenriched mixture of BDDE stereisomers or in an enantiomerically pure BDDE. Enantiomerically enriched or pure BDDE is useful as a cross-linking agent, such as in the preparation of a cross-linked hyaluronic acid product.
