So what you've got here is something a lot of labs keep coming back for, and honestly, most buyers go with teh 10mg vials because they're good middle ground for most work—you just reconstitute what you need and store the rest at -20°C.
It's got CAS number 107761-42-2 and a molecular weight right around 4514.04 g/mol, and that 99% or better purity is confirmed by HPLC on each batch so you're not guessing about what's in the vial.

We usually have stock on the 5mg, 10mg, and 20mg vials, but the 20mg runs out faster (usually 2-4 weeks lead time if we're low), so check before placing a big order.

One detail that people don't always think to ask is that this isn't really suited for anything beyond research use—it's research grade, not pharmaceutical grade for human or animal administration, and the COA spells that out.

The lyophilized powder looks pretty standard, white and fluffy, and if you store it dry at -20°C you'll get the full 24 months of shelf life, maybe a bit more if your freezer is stable.
Anyway, for ordering we just need to know the vial size and quantiy, and our company can do 10 as standerd packging, or custom amounts if you're looking at larger volumes.
We can do as few as 10 vials per box for 20mg, but if you need a single vial, just reach out—we can sometimes accommodate smaller trial orders.
Yes, every batch comes with a CoA showing ≥99% purity by HPLC. Just request it when you place your order, and we'll include it in the shipment.
Lead time is typically 2-3 weeks from order confirmation, depending on batch size and current workload. We'll give you a firm timeline when you place the order.
Sure, we can customize vial sizes to your specs—just let us know the exact amount you need per vial. Minimums may apply for non-standard packaging.
Once reconstituted, keep it refrigerated at 2-8°C and use within 7 days. For longer storage, freeze at -20°C in single-use aliquots to avoid freeze-thaw cycles.
