Optical Purity Measuring Reagents

Optical Purity Measuring Reagents — includes aromatic carboxylic acids and amino acid protecting-group derivatives used as derivatizing agents for chiral compounds. The conjugated aromatic groups in some of these reagents allow observation of exciton interactions via circular dichroism spectroscopy.

Optical purity measuring reagents are used by analytical chemists and asymmetric synthesis researchers to determine the optical purity and absolute configuration of chiral compounds through the exciton chirality method and the formation of diastereomeric esters or amides analyzed by HPLC or NMR. Substituted benzoic acid derivatives and Boc protecting reagents are commonly used in the sample derivatization step prior to analysis.

Select reagents based on the reactive group that matches the target functional group on the chiral molecule (alcohol, amine, or acid), as well as high purity to minimize interference in analysis results. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
