Palmatine chloride hydrate

Palmatine chloride hydrate (Palmatine) is suitable for use:

• as alkaloid standard in the method validation for determination of berberine, hydrastine and canadine in goldenseal (Hydrastis canadensis L.) root powder
• in the preparation of 8-heteroaryl-7,8-dihydroprotoberberine
• in a study to investigate the FT-Raman and surface-enhanced Raman scattering (SERS) spectra of three related alkaloid dyes, namely palmatine, jatrorrhizine and coptisine

Palmatine chloride hydrate (Palmatine) is an alkaloid. It is a potential phototoxin, and exhibits low quantum yields for fluorescence. Normal Raman spectra and DFT calculations of palmatine chloride hydrate is reported.
