Dear Eyu,

I think attached papers are useful for solving your problem.

Sincerely yours, Homayoon.

Christian Q. Scheckhuber

I highly recommend 70 % DMF or EtOH. The reason is that the NBT does not fully dissolve in water.

Dear Mr Proteek Dasgupta ,

Can the calculation example you provided for NBT be applied to calculate for other solutions' preparations?

Regards, Sobiitraa

Proteek Dasgupta

Hey @Sobiitraa Devii

You can calculate other solutions with the same calculation. You just need to be careful of the solvents and solutes you're using and the total desired volume of solution you need. Also the molecular weight needs to be checked on the bottle label.

Sorry for the late reply

Cheers!!
