Researchers reconstituting that white powder to run binding assays need to plan ahead, since we've got a 1kg minimum and that's basically a pallet's worth for most labs, but if you're scaling up a screening cascade or sub-contracting prep work it makes the per-gram cost much better (usually 20-30% below smaller lots).
Actually, we hold steady stock of the -20°C sealed containers flushed with inert gas, so lead time is roughly 10-14 business days if you're in North America or Europe—confirm for Asia-Pacific because customs can add a week or so depending on the port.
It's a white to off-white powder, HPLC showing ≥99.9%, and that's tighter than most standerd peptide batches we see come through, which is what your QC team will want when they're verifying receptor binding data or running stability studies over 3-6 months.
Molecular weight sits at 4113.6 g/mol with the CAS 2381089-83-2, so it's not the same as commerical grade you'd compound for human use, and honestly it's overkill if you're just doing a quick ELISA validation—stick with smaller gram lots for that.
We've had buyers use this for custom labeling projects (tritium or dye conjugation) and they tell us the high purity cuts out a lot of cleanup steps, but you'll want to aliquot it under a dry nitrogen stream if you're opening the whole keg at once—moisture creep is a real thing at this scale.
One thing you won't see on the spec sheet: the powder compresses slightly under its own weight during transport, so the 1kg container might look about 80% full when it arrives, but teh mass is all there and a quick re-weigh on your balance will confirm it.
The 1kg MOQ is due to the complexity and cost of synthesizing pharmaceutical-grade semaglutide at ≥99.9% purity. It ensures consistent batch quality and efficient production runs for serious research labs.
Lead time is usually 4-6 weeks from order confirmation, depending on current synthesis schedules. We'll confirm a specific timeline when you place the order.
Yes, every 1kg shipment includes a CoA detailing HPLC purity (≥99.9%), appearance, and molecular weight verification. Third-party testing reports are available upon request.
Keep it at -20°C in the sealed container under inert gas, protected from light. Avoid freeze-thaw cycles. Under these conditions, it's stable for at least 24 months.
For the 1kg MOQ, we ship in a single sealed container under inert gas. If you need smaller aliquots, we can pack in multiple containers at no extra charge—just let us know.
Just outstanding experience with this order! The delivery was incredibly fast, arriving well ahead of schedule, which made my lab's workflow much smoother. Juggling tight deadlines, I was thrilled with how promptly everything was handled. The quality of the product appears top-notch upon initial inspection, with no visible issues or impurities. Moreover, the customer service team was highly responsive and professional, answering all my queries without delay. Jovial and efficient interactions made the entire process a breeze. I'd definitely recommend this supplier for their reliability and excellent support.
