1-gram samples run about $180 per gram, 5-gram mid-tier orders drop to around $140, and once you're over 25 grams we're pricing at roughly $110 per gram but that depends on your MOQ and payment terms (usually net 30 for established labs).
The HPLC purity comes in at ≥99.0% with single impurities capped at ≤1.0% — that's tighter than most reference standard we see from other bulk suppliers, and it basically means you're not wasting time troubleshooting unexpected side reactions from low-grade materail. We batch-test every production run. 4731.33 g/mol molecular weight and the full C221H342N46O68 formula. Peptide content runs ≥80.0% with moisture held to 10% or below, so rehydration is predictable.
Storage is straightforward: keep it at 2-8°C in a dry enviroment and you'll get consistent stability for 18-24 months. Don't store it at room temp, it's not designed for that and you'll degrade the peptide content faster than you'd expect. We usually have 1-kilogram batches in stock but the 5-gram quantities are what most early-phase buyers go with first.
For ordering, you can specify vial or bag packging — teh bags are easier for larger amounts but vials minimize headspace for smaller runs. Lead time is about 10 days or so for quantities under 100 grams, maybe 20 working days if we need to schedule a new synthesis run. CAS is 2381089-83-2 if you're cross-referencing against your library.
It's not suited for anything beyond controlled laboratory work — no human or veterinary appliction, and purity specs are tuned for research use, not pharmaceutical formulation. We've seen a few groups try it in oral delivery setups and it just doesn't perform there, so stick with your established in vivo or in vitro protocols.
We typically start at 1 gram for research orders. If you need a smaller or larger quantity, reach out to us and we can work something out.
Yes, every batch comes with a COA showing purity, single impurity, peptide content, and moisture content. We can also share HPLC and MS data upon request.
We can do custom packaging and labeling for bulk orders, just let us know your requirements. For smaller research quantities, we pack in standard sealed vials or bags.
For in-stock items, we ship within 3-5 business days. Larger or custom orders may take 10-14 days depending on production and testing.
Keep it at 2-8°C in a dry environment, away from moisture and light. Proper storage ensures the peptide stays stable and meets its ≥99% purity for research use.
