ChiraDex® is a versatile HPLC column characterised by broad enantioselectivity and can be used for the separation of enantiomers of numerous different classes of substances. ChiraDex® is based on beta-cyclodextrin covalently linked to spherical particles of silica, and is ideal for chiral separation of hydrocarbons, steroids, phenol esters and derivatives, aromatic amines, heterocycles with five- to seven-membered ring. Simply composed RP-eluents can be used in most separations.

Supplier: Avantor

Useful for the analysis of chiral compounds in fragrances, pesticides and pharmaceuticals in which the determination of the ratio of enantiomers in a sample is necessary.

Supplier: USP

USP Reference Standards are specified for use in conducting official USP–NF tests and assays. USP also provides Reference Standards specified in the Food Chemicals Codex as well as authentic substances—high-quality chemical samples—as a service to analytical, clinical, pharmaceutical and research laboratories. To confirm accuracy and reproducibility, USP Reference Standards are rigorously tested and evaluated by multiple independent laboratories including USP, commercial, regulatory, and academic labs. USP also provide publicly available, official documentary standards for pharmaceutical ingredients in the USP–NF that link directly with our primary reference standards.
