Liquid liquid chromatography is a combination of liquid liquid separation principles combined with the methodology of chromatography. In this technique, separation occurs between two immiscible liquid phases, as both the mobile and stationary phases are liquids.

API: Steroid
Goal: Purification
A microbiological fermentation process produces this API. However, if reaction selectivity is compromised, stereoisomer of the API and other by-products appear in the process. Conventional production techniques of this API require steps that result in a significant loss of the yield. During the last step only, which is a preparative HPLC step, the loss is 70%. Using our CPC method, a yield of above 90% can be achieved with the similarly high purity. Because of the remarkable selectivity value, the system can be loaded well despite the low solubility of the API.
Lipid nanoparticles (LNPs) are novel powerful pharmaceutical drug delivery vehicles, intensively utilized in the formulation (i.e., encapsulation) of mRNA vaccines. These systems primarily rely on four lipid components: a PEG lipid, amino (cationic) lipid, structural lipid, and cholesterol [1]. The ionizable (cationic) lipids are key components in LNPs, since they can form aggregate complexes with nucleic acids through a charge-charge interaction (Fig. 1).
In an ongoing feasibility study an alkane/alcohol/water solvent system based multiple dual mode (MDM) CPC method was developed to isolate a cationic lipid with a proprietary structure from a synthetic reaction mixture (containing unreacted starting material and over-alkylated byproducts as major impurities). The CPC method outperformed the currently used normal-phase flash chromatography in terms of yield and circumvented the stability issue experienced on solid stationary phase column chromatography with dichlormethane-methanol solvents.
In summary, 320 mg of lipid crude was processed in 35 min to produce the target lipid in 93% yield and with 98% purity on a lab-scale CPC system (Fig. 2). The scale-up of this promising methodology to pilot-scale is currently in progress.
