Someone running binding assays or in vivo metabolic studies will reconstitute this with bacteriostatic water, typically at concentrations that match their dose-response curve requrement, and it holds up well in solution for about 72 hours if refrigerated — we've had labs push it to 5 days with no visible degradation, but I'd stick to the shorter window for consistency.
We're ordering the 20mg vials because most buyers go with that size for chronic dosing studies, and the white powder reconstitutes cleanly with no visible aggregates or floaters, which is something you only notice after handling a few batches form different supliers.
The CAS is 2023788-19-2 and purity specs come in at 99.9% by HPLC, but what actually matters is that the COA shows no residual solvents above 50 ppm and the endotoxin levels are under 1 EU/mg — these are the specs that trip up cheaper sources.
MOQ is 10 vials per spec, so you can order a single box of 10mg or mix sizes if you talk to rep first, and lead time is usually 7-10 business days but confirm before committing to a tight timeline.
And it's not really suited for large-scale synthesis work because the 10mg and 20mg vials are clearly meant for individual reconstitution — if you need gram quantities, you're better off looking at teh raw API in bulk, which isn't listed here.
The molecular weight is 4813 g/mol, which is about what you'd expect for a 39-amino-acid peptide with the fatty acid diacid modification, and the 10mg vial gives you roughly 2.08 micromoles per vial if you're doing molarity calculations.
We guarantee a minimum purity of 99.9% by HPLC for every batch. If you need a COA showing the exact purity, we can provide it with your order.
We can customize the packaging to include a mix of vial sizes in one box—just let us know the quantities of each strength you need. The MOQ of 10 vials still applies, but they don't all have to be the same size.
For 100 boxes, typical lead time is 7-10 business days after order confirmation and payment. If you need it faster, we can sometimes expedite for a small rush fee—just reach out.
Yes, we can supply the Certificate of Analysis (COA) and Material Safety Data Sheet (MSDS) for this batch upon request. Just let us know before shipping, and we'll include them in the package.
Store the powder in a cool, dry place at -20°C, away from light and moisture. Properly stored, it remains stable for up to 24 months. Once reconstituted, use it within 2-3 weeks if refrigerated.
