This lot came off our GMP line last quarter with 99% purity verified by HPLC — the batch you're looking at was part of a regular production run. CAS 885340-08-9 is the one you'd want to reference on your import docs; we've seen some buyers confuse it with the longer chain versions. Molecular weight comes in at 889.02 g/mol, which matters for reconstruction calculations if you're dosing at sub-milligram levels.
We usually stock the 10mg vials, but teh 5mg and 20mg are availble with about a week lead time or so. Each box holds 10 vials, and each vial is a white freeze-dried powder — no fillers, no bulking agents, just peptide salt. You'll need to store it at -20°C in a dry enviornment; shelf life is 24 months if you're disciplined about not freeze-thawing repeatedly.
One thing buyers don't always ask about is the residual moisture content — ours typically runs well under 2%, which keeps degradation minimal during reconstitution. The 5L option? We don't carry that for this, it's strictly research-grade vials, not compounding-ready solutions.
And while rigorous specs matter, it's also worth noting this isn't something you'd want for in vivo work without your own downstream purification step — our grade is for assay preparation and cell culture studies, not direct administration. Anyway, your RFQ mentioned interest in 5 boxes of 10mg; our company can ship those today, but confirm your preferred carrier for cold-chain handling.
We can do a single box (10 vials) as the MOQ, but if you need a smaller sample, just let us know — we can sometimes work out a trial pack for first-time lab buyers.
Yes, we include a CoA for every batch, showing the ≥99% purity and confirming the peptide identity by mass spec and HPLC. If you need the documents before ordering, just ask.
Lead time is typically 5-10 business days for orders under 100 vials, and we ship with ice packs and thermal insulation to keep the powder stable during transit. For express shipping, we can arrange DHL or FedEx.
We can do custom vial sizes beyond the standard 5, 10, and 20mg, and we can also print your lab’s logo or batch info on the labels. Just send us your specs and we’ll quote the custom run.
Store the powder at -20°C in a dry, airtight container away from light. Once reconstituted, we recommend using it within 30 days if kept refrigerated at 2-8°C, and never freeze the liquid form.
