We're looking at about 4731.33 g/mol for the molecular weight on this one, and the HPLC purity comes in at 99% or better — we've seen consistent results across batches, roughly 99.2% on the last three runs, which is tighter than some supliers manage for this sequence.
The white powder form is what you'd expect, and it's pretty straightforward to handle, but you'll want to keep it at 2-8°C in a dry enviornment — we usually have stock, but confirm lead time if you're ordering over 50 grams, as bulk orders can take 20 days or so.
Most buyers go with the 10mg or 50mg vials for smaller runs, though we can do 1g or 5g bags if you're scaling up — what it does is save on reconstitution time, and peptide content is typically above 80%, which is better than reagent grade for this.
Actually, one thing people don't always ask about is the single impurity level — it's under 1%, so you're not dealing with major side peaks, but we don't recommend this for anything beyond research use, as it's not formulated for in vivo work or anything like that.
Also, the sequence has that diacid-C20 modification on teh lysine residue, which is a bit unusual — it's not something you see on every GLP-1 analog, and we've had a few buyers ask about batch-to-batch consistency on that specific part, so our company provide a COA with each shipment.
Bulk pricing kicks in at 100 grams or so, and our company can do custom packaing if needed — lead time is about 2-4 weeks for larger quantities (check lead time for orders over 200g), and we ship with an SDS and TDS included.
