Specific Rotation: Yidian Wuguang
Polarimetry is a method that uses the optical rotation phenomenon when plane-polarized light passes through a liquid or solution containing certain optically active substances (such as compounds with asymmetric carbon atoms) to measure drugs or check their purity, and can also be used to determine content.
Mainly used for: drug identification, impurity inspection, and content determination.
Specific rotation is an important physical constant of optically active substances, which can be used to distinguish drugs or check their purity, and can also be used to determine content. The optical rotation of a substance is not only related to its chemical structure but also to the concentration of the solution, the path length of the light, as well as the temperature and wavelength of the polarized light during measurement.
Unless otherwise specified, this test follows the Chinese Pharmacopoeia 2020 Edition, Part IV - 0621 testing standard.
