Pine Chemicals & Turpentine Derivatives
Alpha Pinene Laevo
Laevorotatory isomer
Description
Alpha Pinene Laevo is the laevorotatory form of alpha pinene, separated where the optical activity of the material matters to the reaction it feeds. Chemically it is the mirror image of the dextro form, and the two behave differently in stereoselective synthesis.
It is taken principally by aroma chemical makers and fine chemical producers whose downstream route depends on starting from a defined isomer rather than a mixture.
