CAS 2023788-19-2 is the identifier you'll cross-reference with your own reference standerd, and our company supply it as a lyophilized white powder with >99% purity verified by HPLC—every batch ships with a COA. Teh molecular weight sits at about 4113 g/mol, which matters when you're calculating molar concentrations for dose-response work or binding assays.
Most buyers go with the 10mg or 20mg vial for reconstitution, though we also stock 5mg, 15mg, and 30mg depending on your typical yield needs. It's not suited for oral dosing in any form—this is strictly for injectable or in vitro research protocols, and we recommend reconstituting with sterile water or bacteriostatic water at 0-4°C immidiately after opening.
Storage is straightforward: keep it dry and dark at 0-4°C for short-term use (usually 2-4 weeks) or -20°C for longer preservation—shelf life exceeds 2 years when handled properly, but avoid repeated freeze-thaw cycles because that degrades the peptide backbone faster than most people expect. We've seen labs lose potency after three cycles, so aliquot it if you're running multiple experiments.
A detail buyers don't always ask about: powder is hygroscopic, so minimize air exposure when weighing or reconstituting—use a desiccator if you're not using the whole vial at once. 5. Lead time is typically 7-14 days for UK dilevery, and we usually have stock on the 10mg and 20mg vials, but confirm availability if you need 30mg—that one moves slower and might require a short wait.
