For a single vial, you're looking at about $85, give or take, but if you step up to 5 vials it drops to $65 each and at 20 vials our company can do $48 per vial — that's where most buyers go, honestly.
98% purity by HPLC is the floor, not the ceiling, and we've seen batches run tighter than that. It's a white to off-white powder, soluble in both water and organic solvents, which basically means you can reconstitute it however your protocol demands without fighting solubility issues. Storage at -20°C protected from light is non-negotiable, and we usually have stock, but confirm lead time if you need more than 50 vials at once. The 24-month shelf life assumes you don't leave it out on the bench for a week.
What it does is give you a consistent starting point for dose-response work, and the COA form each batch is availble before you even open teh vial. We don't include NMR or MS reports by default, but you can request them and we'll email a PDF within a day or so.
It's not suited for anything involving cell culture at physiological pH for extended periods — the stability window narrows once reconstituted, so plan your aliquots accordingly. Also, the 5mg vial is actually easier to handle than the 10mg if you're working with small volumes, but that's a preference thing.
Sealed under inert atmosphere in vials, so you're not fighting oxidation before you even open it. Most researchers we deal with just store it in a -20°C freezer and pull what they need, but don't let it sit at room temp for more than a few minutes.
Anyway, the CAS is 1401708-83-5 and molecular weight is 504.67 g/mol, which matters if you're calculating molar concentrations for binding assays.
