Collection: Chiral Resolution Reagents
Chiral Resolution Reagents — encompasses non-racemic chiral compounds such as amino acids, terpenoid carboxylic acids, chiral amines, and alkaloids used as agents to separate enantiomer pairs through the formation of salts or diastereomeric complexes. This group forms the backbone of classical resolution techniques in asymmetric synthesis for obtaining compounds with high optical purity.
Chiral Resolution Reagents are used by synthetic chemists and pharmaceutical process developers to separate racemic mixtures into single enantiomers through crystallization of diastereomeric salts, for example reactions of camphorsulfonic acid or tartranilic acid with racemic amines, or chiral amines such as bis(1-phenylethyl)amine with racemic carboxylic acids. These reagents also serve as chiral auxiliaries or derivatizing agents for determining the optical purity of products from asymmetric synthesis.
Example products in this collection: TCI A0546 56-84-8 L-Aspartic Acid, TCI B6685 23294-41-9 Bis[(R)-1-phenylethyl]amine, TCI V0014 72-18-4 L-Valine, TCI C0012 124-83-4 (+)-Camphoric Acid, TCI V0012 640-68-6 D-Valine, TCI C0015 3144-16-9 (+)-10-Camphorsulfonic Acid, TCI T1702 3019-58-7 (2R,3R)-Tartranilic Acid [for optical resolution], TCI C0347 485-71-2 Cinchonidine.
Selecting a resolving reagent requires considering the absolute configuration (R/S or D/L), the enantiomeric purity level, and the compatibility of acid-base functional groups with the target racemic compound so that diastereomeric salt formation proceeds effectively. All products are genuine products of Tokyo Chemical Industry (TCI) Japan, with purity, packaging, and storage conditions listed on each item's page.
