This title was first published in 2001: In the early 20th century the relevance of chirality to the pharmaceutical industry was established by the fact that one enantiomer of hyoscyamine possessed greater pharmacological activity than the other. Today, most new drugs and those under development consist of a single optically active isomer, and chirality is also becoming an issue for the agrochemical and other industries. Regulatory agencies throughout the world are currently reviewing the importance of chirality with regard to pharmaceutical and agrochemical products. New guidelines from such agencies have been key drivers for the focus on single enantiomer products in these industries. These scientific and regulatory developments have created the need for a guide for workers in the pharmaceutical and chemical industries seeking information on chiral molecules, processes, and commercially available chiral chemicals. "Chiral Intermediates" presents the chemical professional with a comprehensive listing of over 4700 available chiral chemicals including specific data of interest for each entry in the listing. Its companion volume, "Chiral Drugs", presents the same detailed information for over 2000 chiral drugs.
