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.
