Hello Ron,
Do you have any idea as to the shelf life of SDA3057 and SDE8006 as a 1% solution in methanol, refridgerated and in brown glass ?

Probably a few years. Without refrigeration and dark glass, you reduce that to months though.

I do mix up only small quantities, so I order 1 gram and make up a solution using 100 mg.
