I have a stock solution of GlcN1P prepared in dH20 and stored at -20°C. From this I make a working solution in 0.9% NaCl which I use immediately or store at -20°C. I use this as a standard in HPLC. My question is how stable is this solution?

I personnaly investigated the stability of Glucosamine H2SO4-KCl raw material, but I did not publishe this work. It is very stable material. Just observe the Alpha and Beta form using LC-UV using derivatization procedure.
If you are interest, email me and I shall send you the analysis method.
