I am looking for an estimate of the above, with BHT (inhibitor), and without, once the bottle has been opened. Thanks.

Our rules of thumb:

Unstabilized THF - 3 months after opening if bottle is purged with N2 after each time it is used. Generally, the manufacturer gives unstabilized THF a one year shelf life in the unopened bottle.

Stabilized THF - Same as general lab chemicals - 5 years from date of receipt.

Realistically, we go through this stuff so fast it never passes the expiriation date, but, we have never had any problems that were traced to "bad" THF.
