Comes lyophilized as a white powder stored at 2-8°C, protected from light, and it's got a shelf life of 24 months if you keep it dry—we usually have stock, but confirm lead time (check the COA for exact specs).

Purity runs at least 99% by HPLC, and that's backed up by MS and a full COA with every batch; the 10mg vials are the most common pick for most protocols, but you can get 2mg, 5mg, 15mg, 20mg, or 30mg depending on your needs.

This isn't suited for anything beyond research use, and the MOQ is one box of ten vials. So, if you're running pilot studies, the 2mg or 5mg sizes are actually easier to handle without wasting material.
The qualiy control here is tighter than what some supliers push out—each batch gets its own HPLC trace, and we've found that the lyophilized format keeps it stable during transit (usually 2-4 weeks lead time on custom orders).

One thing buyers don't always ask about is that teh powder can clump if exposed to moisture—so reseal imediately after use, and it's fine. That's pretty much it for critical details.
