Runs at ≥99% purity by HPLC, which is better than reagent grade for this type of work — we've had buyers switch from lower-grade sources and notice fewer baseline shifts in their assays. CAS 2023788-19-2, molecular weight 4813, and it's a white powder that stores at 2-8°C short term or -20°C long term, with a shelf life over two years if you keep it sealed and cold. Availble in 2mg, 5mg, 10mg, 15mg, 20mg, or 30mg per vial.
So typical buyer is someone running metabolic or receptor studies who needs consistent dosing across replicates. Basically, we see labs working on GLP-1 or GIP pathways ordering this, but it's not suited for anything outside research use — no clinical applicaion here. One concrete thing you'll notice handling it: the powder is very fluffy, so weigh it carefully if you're reconstituting small volumes.
We usually stock most concentrations, but the 30mg vials can run short about 20 days or so — confirm lead time before ordering if you need a large batch. It ships in boxes of 10 vials, and the packaging is customizable if you need individual vials or different quantities (usually 2-4 weeks for custom orders). Each vial is lyophilized and sealed under vacuum.
Most buyers go with teh 10mg vials for standerd protocols, but the 5mg works fine if you're running low-dose titrations. The documentation includes a COA with HPLC trace and mass spec data, though we don't always have NMR — just ask if you need it. And the molecular formula C225H348N48O68 gives it a peptide mass that's tighter tolerance than many competing sources we've seen.
We can do as little as 1 box (10 vials) for any concentration, including the 30mg. If you need smaller quantities, just let us know and we can work something out.
Yes, we include a COA with every batch that shows the actual HPLC purity results. We can also share the mass spec and NMR data if you need it for verification.
For standard orders of 2mg vials, we usually ship within 3-5 business days. If you need rush delivery, we can expedite it for a small fee.
Keep them at -20°C for long-term storage—that gives you over 2 years of shelf life. If you're using them within a few weeks, 2-8°C in a fridge is fine.
Absolutely, we can customize the packaging and labels for your lab. Just send us your requirements, and we'll adjust the box and vial labels accordingly.
