Half life o acetaminophen - on culture media (Apr/29/2010 )

Hi every body,

Does enyone knows how much an acetaminophen solution (in culture media) can last stored at 4°C? can it be stored for long periods of time? Should it me frozen? or should it be prepared fresly every time?

many thanks in advance!

It's pretty stable in Medium stored in -20. But I guess it also depends on what types of medium do you use
