*Welcome Pipeline readers! No really, if you have a dusty bottle of sparteine, we’ll probably take it 🙂
Our lab uses a lot of (-)-sparteine in enantioselective aldol additions, so we tend to buy large bottles which last us a while. As such, we haven’t had to order (-)-sparteine in a while. But our bottle is getting low (read: there are a few hundred microliters left), and it’s time to order more.
But it’s all gone.
All of it.
No one sells (-)-sparteine anymore. Acros. Fisher. Alfa Aesar. VWI. Strem. TCI. I’m sure I’m missing some, since I don’t actually do the ordering. Our ordering guy called Aldrich specifically, and was able to order three 10 mL bottles (probably the last available in the world).
Well, today we get a letter from Sigma-Aldrich telling us… they’re canceling our order. They’re not selling it anymore either.
What is going on, here? Anyone know why the major (-)-sparteine shortage? Is this all of a sudden or has this been happening gradually? Is this related to the acetonitrile pinch, or is this something different? Anyone got any black market (-)-sparteine they want to, er, not sell to us?
