Dear Colleagues,
This is mainly for those in the Pharma industry. It's interesting
that chemical entities submitted for testing can have quite different purity
criteria within different "chemical cultures". I'd be very interested to
know how lenient or stringent your purity criteria may be. Especially with
regard to the need for a correct NMR. And how certain do you need to be
that it is correct?? Is it different for solids vs library compounds?
I understand that this may be somewhat sensitive information. I'm
happy to post a summary that includes our purity criteria. And if you do
NOT want your reply included in that then please state this clearly!
Many thanks,
Mike
