  • NOVEL PHOSPHATIDYLALKANOLS AND COMPOSITIONS THEREOF
    Publication number: 20170052132
    Abstract: The present invention discloses a composition comprising a compound of formula I and a deuterated solvent. The deuterated solvent is miscible with water in any proportion at a temperature of 20 to 25° C. and comprises less than 5% residual 1H-isotopes. The concentration of the compound of formula I may advantageously be determined by 1H-QNMR. Methods of production of the composition and salts of compounds of formula 1, as well as related analogs and novel reagents and intermediates for the production thereof, are also described.
    Type: Application
