This explains why calcium tartrate crystal deposits are found in wines that have been aged for long periods of time. Cold stabilization is not very effective in the case of calcium tartrate as the solubility of
Addition of mass spectrometry (GC–MS) allows quantification of nicotine based on retention time and comparison of the mass spectrum to a standard (nicotine m/z 162 for the molecular ion and m/z 84 for the base peak representing the pyrrolidine unit). Nicotine tartrate salt is often used as...
The present invention is directed to the tartrate salts of 5,8,14-triazatetracyclo[10.3.1.02,11.04,9]-hexadeca-2(11),3,5,7,9-pentaene: 1 and pharmaceutical compositions thereof. The present invention in particular is directed to the L-tartrate salt, and further to the various polymorphs...
A method of preparation of a highly pure salt of R,R-formoterol L-tartrate is disclosed. The process provides the most thermodynamically stable polymorph by recrystallization of a n
The addition of yeast-cell-wall enzymic digest (yeast hulls) can promote tartrate stability, without cold or other stabilization treatments. In the absence of protective colloids, potassium bitartrate exists in a dynamic equilibrium between ionized and salt states. Sign in to download full-size ...
A method of preparation of a highly pure salt of R,R-formoterol L-tartrate is disclosed. The process provides the most thermodynamically stable polymorph by recrystallization of a novel polymorph.
