We've got the 5mg and 10mg vials ready to ship from stock right now, the 15mg usually needs about 20 days or so lead time if you're ordering a larger batch — just confirm your MOQ so our company can check availability.

It's a white powder at 99% purity with a molecular weight of 246.71, and the CAS is 86-39-5, which is pretty standdard for this type of research compound but most buyers go with the 10mg vials for convenience.

Actually, what you get when ordering is each vial sealed and packed with a cold chain pack — we store everything at 2-8°C protected form light, so it's better than reagent grade for this kind of work, though it's not suited for anything beyond lab use.
COA comes with every batch, and the HPLC data is solid, but we usually have stock on the 5mg and 10mg, while the 15mg might take a bit longer (check lead time for your quantity).

That molecular formula is C13H7ClOS, by the way, and the tighter tolerance than most supliers is something we don't advertise, but it's a detail you'll appreciate when running your protocols.
