Collection: Optical purity/Absolute Configuration Determination Reagents (for NMR)

Optical purity/Absolute Configuration Determination Reagents (for NMR) — contains chiral reagents such as camphanic acid derivatives, trifluoro-anthrylethanol, and CASA compounds, used to determine the optical purity and absolute configuration of a compound through NMR chemical shift analysis.

These reagents are used to form diastereomeric derivatives or association complexes with the target compound, so that the NMR signals of both enantiomers can be distinguished and the enantiomeric ratio calculated. Synthetic organic chemists and stereoselective process developers use them to verify the results of asymmetric synthesis without requiring chiral chromatography.

Example products in this collection: TCI T3002 1244954-13-9 (1S,4R)-1,2,3,4-Tetrahydro-1,4-epoxynaphthalene-1-carboxylic Acid, TCI C1021 13429-83-9 (-)-Camphanic Acid, TCI T1521 60646-30-2 (S)-(+)-2,2,2-Trifluoro-1-(9-anthryl)ethanol [ee Determination Reagent by NMR], TCI C2184 909254-56-4 Chirabite-AR, TCI T1520 53531-34-3 (R)-(-)-2,2,2-Trifluoro-1-(9-anthryl)ethanol [e.e. Determination Reagent by NMR], TCI C3580 1819341-33-7 (R,R)-CASA-H, TCI B1720 95373-54-9 (+)-Benzylmethylphenylsilylacetic Acid [for e.e. Determination by NMR], TCI C3581 (S,S)-CASA-H.

Pay attention to the stereochemical configuration of the reagent (R or S), the enantiomeric purity of the reagent itself, and the suitability of the functional groups with the target compound to be analyzed. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on the page of each item.
