Basically, when researchers are running a series of dose-response assays—say, screening metabolic or GLP-1 related pathways—the 30mg vial tends to be the go-to to avoid running out mid-experiment, and we've seen labs order those in batches of five or so to tie them over for a month.
We typically have stock across all four sizes: 5mg, 10mg, 15mg, and 30mg, and the purity is routinely north of 99% per our COAs, with the molecular weight coming in at 4113.64 g/mol for this C187H291N45O59 sequence—the lyophilized form is the standerd white powder you'd expect, so there's no wiggle room on storage if you want it stable for the long haul.
So it's really not suited for any in vivo work unless you're set up for that specific reconstitution protocol—most buyers go with water for injection or a sterile buffer—and after you reconstitute, you'll want to keep it at 2-8°C; roughly four weeks of usability is realistic, but our company can't vouch for longer if the seal's been broken.
Anyway, the 5mg and 10mg sizes are better for smaller pilot runs given they're easier to handle in a sterile hood—you don't want to waste half a vial on a single test.
We've got an MOQ of one vial on the 5mg, and lead times for the 15mg or 30mg are usually 10 days or so once we confirm teh batch numbers—check COA for your specific CAS 2381089-83-2 lot when it arrives.
