ChromegaChiral CCC is a modified cellulose including the combination of 3-chloro-4 methylphenylcarbamate and 3,5-dichloro- phenylcarbamate bonding groups coated on high purity, high performance spherical silica particles. This combination of bonded groups stabilizes the solubility of coated phase making for a durable phase similar to other widely used coated phases. The use of cellulose modified with chlorinated phenyl groups provides for the separation for many previously unresolved/poorly resolved chiral mixtures by providing unique separation characteristics.
