Chiral stationary phase
WebSome chiral stationary phases (CSPs) are able to separate a wide range of chiral compounds, while others are useful only for specific types of chiral compounds. Normal phase solvents are commonly used for chiral HPLC separations, however, reversed phase solvents can also be used with certain types of chiral stationary phases. Approximately … WebOur ChiraDex® stationary phase is a versatile HPLC column characterized by broad enantioselectivity and can be used for the separation of enantiomers of numerous …

WebThe chiral stationary phase can be prepared by attaching a chiral compound to the surface of an achiral support such as silica gel. Common chiral stationary phases are … WebAstec Cellulose DMP is a chiral stationary phase (CSP) comprising spherical, high-purity porous silica coated with DMPC (3,5-dimethylphenyl carbamate)-derivatized cellulose, and packed in analytical to preparative size HPLC columns. It separates a wide range of chiral compounds under normal phase, polar organic, and SFC conditions, with high ...
Web2 days ago · Chiral chromatography is a type of liquid chromatography that separates enantiomers based on their differences in interaction with the stationary phase. The … WebChiral gas chromatography and high-performance liquid chromatography have paved the way and fostered several research areas, that is, asymmetric synthesis and catalysis in organic, medicinal, pharmaceutical, and supramolecular chemistry. The development of highly enantioselective chiral stationary phases was essential.
WebAn HPLC column was prepared with L-Glu chiral silica gel as the stationary phase and n-hexane-isopropanol (9∶1, v/v) as the mobile phase. Fifteen racemic compounds were successfully separated on the chiral HPLC column, including seven racemic compounds for baseline separation, at a flow rate of 0.1 mL/min using 254 nm as the detection ... WebChiral covalent organic frameworks (CCOFs), built by the condensation reactions of organic building blocks with enantiomeric purity and linking subunits, have emerged as a marvelous category of porous crystalline material. In addition to stability and good porosity, CCOFs possess remarkable enantioselectivity, which would be exploited for asymmetric …
WebApr 4, 2024 · Porous organic cages (POCs) are a new subclass of porous materials, which are constructed from discrete cage molecules with permanent cavities via weak intermolecular forces. In this study, a novel chiral stationary phase (CSP) has been prepared by chemically binding a [4 + 6]-type chiral POC (C 120 H 96 N 12 O 4) with …
WebChromatography using chiral stationary phases (packing materials) is one effective method that is used as a standard method for chiral preparation, but purification cost is a problem for industrial-scale purification owing to the high cost of the stationary phase. YMC has developed high performance packed materials, packed columns, and ... phone lens for eye photographyWebApr 1, 2016 · Chiral stationary phases that are based on amino acid derivatives, cyclodextrins and chiral silanes are capable of separating enantiomers because one enantiomer interacts slightly stronger than the other one with the stationary phase, often due to steric effects or other very specific interactions.
