WebThe resolution of chiral amines can be performed by treatment with a chiral enantiopure carboxylic acid such as tartaric acid (more generally referred to as a chiral auxiliary). ... WebThese regeneration procedures utilize extended range solvents like DCM, DMF, or EtOAc to help restore the columns original performance. It is important to note these procedures can only be utilized with the immobilised CHIRALPAK ® chiral columns, and will result in irreversible damage to any coated CHIRALPAK ® or coated CHIRALCEL ® column.
