Miles Holborough-Kerkvliet I assume that all listed reagents are stable in solution. I suggest that you store the solutions of THTPA and the Azide in the refrigerator at ca. 0 °C. The other reagents should be stable at room temperature.

Dear all, if you have a doubt about the stability of these reagents, you Can simply check the net for that, every thing is available. I give you an exemple of the following link for THPTA, you can do the same for the others. In doing so, you will get a broad vision on the natural of these chemicals, your safety is much more important than their stability. Caution: if you are not familiar with chemistry, becarefull in manipulating azides. My Regards

Frank T. Edelmann Abdelkader BOUAZIZ T. H. Al-Noor Devidas Bhagat thanks for all your responses. They are very useful and help me out a lot! Will read the links you all provided.!

Hi ;

I fully agree with Professor Frank T. Edelmann. All solutions except THTPA and AlexaFluor-647 Azide can be stored at room temperature (15°C in winter; 30°C in summer). These products are stable and are considered non-reactive at normal temperatures and pressures. However, THTPA and azide solutions are stable for several weeks when frozen.

With my best regards

Doufnoune RACHIDA Rachida good to see that we agree in all points! 👍
