We've been running these through HPLC and MS, and the purity consistently hits 99% or better—that's verified against a reference standard, not just a number we pulled form a spec sheet. CAS is 910463-68-2, and the molecular weight comes in at 4113.58 g/mol, which matters for accurate reconstitution if you're doing dose-response work.
Storage is pretty straightforward: -20°C for long term, but you can keep it at 2-8°C for a few weeks or so without degradation. It's a, and what it does is dissolve readily in water or buffer—basically no issues there. We include the COA with every order, and if you need the full TDS or SDS, just ask.
Each vial holds 10mg, and the MOQ is 10, though our company can customize that if you're running a larger study. The packaging uses sterile vials with tamper-evident seals, which is standard for this type of product. Most buyers go with the 10mg format since it's convenient for single-use reconstitution.
One thing to note: this is for research use only, not suited for human or veterinary appliction. We've had a few labs ask about retesting, and we do offer a retest policy within 12 months of manufacutre—just confirm the lead time if you're ordering a batch older than 6 months. The powder stays stable for up to 24 months at -20°C, give or take.
Also, we usually have stock on the 10mg vials, but larger quantities might take 20 days or so to produce. Batch consistency is tight—better than some reagent-grade peptides we've seen—and every batch gets an endotoxin test as well as HPLC purity. You'll get the analytical data with shipment, no need to chase us for it.
