So you've been looking into tirzepatide for your metabolic studies, and honestly, the >98% purity on this batch is what sets it apart from a lot of what's floating around out there—we've seen some suppilers pushing stuff that barely clears 95% on HPLC, which can throw off your dose-response work pretty badly.
The molecular weight sits at 4813.45 g/mol, and that CAS number 2023788-19-2 is one you'll want for any documentation or ordering systems you've got set up, and we usually have stock, but confirm lead time if you need more than 50 grams or so since can vary by a week or two depending on the quarter.
It's basically not ideal for anything involving solubility testing right now since that's still listed as to be determined in research, so you'll want to have your own vehicle control figured out before you start, but most buyers go with it for diabetes and metabolic disorder studies where the dual GIP/GLP-1 mechanism actually shows better glucose control than the single-target peptides.
Storage is straightforward but critical—keep it at -20°C protected form light, and we've seen folks who ignore that end up with degraded materail in about three months, whereas properly stored it'll hold for over two years, and teh white powder appearance is consistent across batches we've handled.
One thing you might not think to ask is that the shelf life spec assumes you're not freeze-thawing it repeatedly, so aliquot it out when you first get it, and we usually recommend 10mg or 20mg vials depending on your typical dosing range.
