So you're looking at the 10mg/vial lyophilized powder — we've been supplying this to labs in the US and EU for a while now, and it's the same materail we ship to a few major contract research organizations out of our ISO-certified facility, and we know the compliance side can be tricky, so we always include a full COA and can provide SDS/TDS along with any other docs customs typically asks for, and we usually have 100-200 vials in stock for immediate dispatch, but for larger quantities you'll want to give us a 2-week lead time or so.
The typical purity as tested by HPLC is ≥99%, and it's pretty much what you'd expect for a pharmaceutical-grade reference standard — we've seen some buyers use it for receptor binding assays or dual agonist mechanism studies, and the 10mg per vial works fine for pulse dosing in vitro work, but honestly it's overkill if you're just running a quick screening panel, and we don't recommend it for anything involving live animal models unless you've got the dilution protocols dialed in.
4813.47 g/mol is the molecular weight, CAS is 2023788-19-2, and the stuff is soluble in water at reasonable concentrations — most people reconstitute it at 1-2 mg/mL without issues, but we've noticed that if you let it sit at room temp for more than 30 minutes it tends to degrade faster than some GLP-1 analogs (that's a known limitation with teh PEG-modified backbone), and we always store our bulk inventory at -20°C in light-protected containers, which is what the spec sheet says anyway.
There's actually a batch-to-batch variability in lyophilization process that we don't advertise — sometimes the cake looks slightly different, but the HPLC still shows the same purity, and we've flagged this to a few EU buyers who were concerned about appearance, and they confirmed it doesn't affect performance, so it's one of those things you'd only know if you handled it regularly.
About 30-40% of our US clients ask for custom packging — smaller or larger vials, sometimes with pre-measured buffer, but our company can't do everything in-house so we usually point them to our 10mg/vial format unless they're ordering 500+ vials, which triggers a production run anyway, and for import to the UK we've seen customs ask for the SDS and a letter of research use only, which our company provide as standard.
We can do single vials for sample orders, but our standard MOQ is 10 vials for production runs. If you need a custom quantity, just let us know.
For standard orders, lead time is 3-5 business days after payment. Custom packaging or larger bulk orders may take 7-10 business days.
Yes, each batch comes with a Certificate of Analysis (CoA) showing ≥99% purity by HPLC, and we can also provide MSDS and other docs upon request.
Absolutely. The standard is 10mg per vial, but we can customize the fill amount and vial labeling to match your needs—just specify when ordering.
Store it at -20°C in a freezer, protected from light. If reconstituted, use it quickly and keep it refrigerated. Avoid freeze-thaw cycles.
