However, this is changing as more cannabinoids are identified, and compounds such as cannabichromene and cannabicyclol are emerging as potential investigatory candidates for varying indications. Because these molecules are chiral, the separation and study of the individual enantiomers\u2019 biological and physiological effects should therefore be of interest. The purpose of this study was to identify analytical separation conditions and then adapt those conditions to preparative separation. This was accomplished with a column-screening approach on Daicel\u2019s immobilized polysaccharide chiral stationary phases using non-traditional mobile phases, which included dichloromethane, ethyl acetate, and methyl tert-butyl ether under high-performance liquid chromatography conditions. CHIRALPAK\u00ae IK was found to separate all four compounds well with mobile phases containing hexane-dichloromethane (with or without an acidic additive). From these methods, the separation productivities were calculated to better visualize the separation scalability, which shows that the kilogram-scale separations of each are feasible.<\/jats:p>","DOI":"10.3390\/molecules28031164","type":"journal-article","created":{"date-parts":[[2023,1,25]],"date-time":"2023-01-25T03:23:49Z","timestamp":1674617029000},"page":"1164","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Chiral Separation of Cannabichromene, Cannabicyclol, and Their Acidic Analogs on Polysaccharide Chiral Stationary Phases"],"prefix":"10.3390","volume":"28","author":[{"given":"John M.","family":"Ferraro","sequence":"first","affiliation":[{"name":"Chiral Technologies, Inc., 1475 Dunwoody Drive, Suite 310, West Chester, PA 19380, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4044-8099","authenticated-orcid":false,"given":"Weston J.","family":"Umstead","sequence":"additional","affiliation":[{"name":"Chiral Technologies, Inc., 1475 Dunwoody Drive, Suite 310, West Chester, PA 19380, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1093\/toxsci\/kfr088","article-title":"Thalidomide: The tragedy of birth defects and the effective treatment of disease","volume":"122","author":"Kim","year":"2011","journal-title":"Toxicol.
