the IPA commonly available at drug stores is usually 90-91%,I believe,at
least in the US.


50%, 70% and 90%. I have asked several drug stores about getting
purer IPA and was told 90% is the best they can get. I use a lot of 90%
to prep for insulin shots, so I try to keep three or four bottles on
hand. There are times that I can't find 90% for a couple months at a
time.
