We've been supplying this to labs running metabolic pathway work for a while now, and most researchers go with the 5mg vials first—about 50 units or so is a common order to get started, but our company can do smaller MOQs if you're still in early screening.

You'll want to keep it at -20°C in teh lyophilized form, basically straight out of the freezer it's good for months, but once you reconstitute it in buffer you’re on a clock—usually 2-4 weeks before you see degradation, and it’s not ideal for anything involving long-term cell culture at room temp.

purity we guarantee is ≥99.9% by HPLC, and what that means for your receptor binding work is tighter tolerance than reagent grade stuff—you can trust the dose-response curve won’t have extra peaks messing with your data, which saves reruns.
CAS is 910463-68-2 on the batch COA, and the molecular weight runs about 4113.6 g/mol—mostly C187H291N45O59 if you’re checking the formula, and we include that spec sheet with every shipment whether you ask for it or not.

Packaing is customizable so you can get it in vials or bottles (or even smaller tubes if you request ahead), but the stays stable longer if you stick with sealed vials—and we usually have stock, but confirm lead time for odd sizes.
