You're looking at a GLP-1 receptor agonist with a prolonged half-life compared to liraglutide, and that structrual modification—the addition of a fatty acid chain—is what drives its sustained activity in metabolic studies, so if your work involves chronic dosing models or long-term glucose regulation assays, this is usually the peptide people reach for.
We've been supplying this for years, and what I can tell you is that the lyophilized cake should be a clean white powder when it arrives, and we run HPLC to confirm that >99.9%—that purity matters because even trace impurities can throw off your receptor binding data in a dose-response curve.
2-8 weeks is typical lead time for custmized bulk orders, though we usually have stock for smaller quantities like 100mg or 500mg vials, and the MOQ on those is pretty flexible—just check with us before you place a rush order.
Storage is straightforward but non-negotiable: keep it at -20°C in a dry enviornment, and once you reconstitute with sterile water, use it within 24 hours or so, because the peptide degrades quickly in solution even if you refrigerate it—I've seen researchers lose a whole batch by leaving it at room tempearture overnight.
One thing buyers don't always ask is that this grade is not suited for any in vivo work in humans—it's strictly for research use only, and our company provide a COA with each shipment that includes the HPLC trace and residual solvent analysis, so you can verify the specs yourself.
Anyway, the molecular weight is 4113.58 g/mol, and the CAS is 910463-68-2, but what really matters for your assay is that teh solubility in sterile water is excellent at concentrations up to 10mg/mL or so, and the peptide is stable for months at -20°C if you keep the vial sealed.
