Glucosamine is described in Merck Index with references but no pKa data
given in the book. Your CAS number is for the hydrochloride.
Tromethamine is TRIS buffer, described in Merck Index: pKb 5.91; pKa 8.3.
Based on your CAS number (but not name), here is a source for one of your
others:
http://www.chemacx.com/chemacx/default.asp?formgroup=basenp_form_group&dbnam
e=chemacx&dataaction=query_string&field_type=TEXT&full_field_name=Substance.
CAS&field_value=488-43-7
(You may need to reconstruct that divided URL in your browser.)
It says 6 sources, including via TCI online.
STN Registry file says your other CAS number is actually
"2-[(Diethylamino)methyl]phenol"
Is that what you want? Or do you want the compound you named (which looks
strange, apparently being a dialkoxyamine)?
Are you the co-author of the C-13 NMR book with Kalinowski? Good book, which
I use frequently, and the best C-13 NMR textbook available.
