What it actually does is block the stress hormone receptor in cell-based assays, so researchers use it to study CRF signaling pathways without the compound degrading too fast in solution—it's pretty stable in DMSO for a week or so at -20°C, which is better than some analogs we've handled.
Purity runs at 98% by HPLC, and we typically see batch-to-batch variation of less than 0.3% on that number, though the exact molecular weight isn't listed on COA (check if you need it for molar dosing). Most buyers go with teh 1g MOQ for initial screening, but we've shipped 50g orders to labs running chronic infusion studies.
It's not suited for anything in vivo or clinical work—this is strictly a research tool for binding assays and cell culture experiments where you need a selective CRF-R1 antagonist. The powder itself is a fluffy white solid, and we've noticed it can pick up static charge in dry climates, so weigh it in a humidity-controlled hood.
We usually have stock in both EU and US warehouses, but confirm lead time if you're ordering more than 500g at once because those sometimes ship form our China facility instead. 2000kg monthly production means our company can handle bulk contracts, but the 1g MOQ (roughly $180-250 depending on current pricing) keeps it accessible for small labs.
Anyway, it's a solid choice for anyone new to CRF antagonist work—the HPLC purity and pre-cleared import docs mean you won't waste time troubleshooting contamination or customs delays. Just remember it's a research chemcial, not a pharmaceutical intermediate, so don't expect it to work in whole-animal models without proper formulation.
Our MOQ is 1 gram — that's the smallest amount we can ship. No exceptions below that, as it's the minimum for our lab-grade packaging and handling process.
From our EU or US warehouses, you're looking at 3-7 business days on average, depending on your exact location. No customs delays since it's already in-country.
Yes, we include a COA showing the 98% HPLC purity result for every batch. Just let us know if you need it before shipping, and we'll send it along.
We do offer customization — packaging options like bags, barrels, or OEM labeling are available. Just tell us your specs, and we'll adjust the order accordingly.
Stock is kept in our EU and US warehouses, so for 1 gram orders, we usually ship within 1-2 business days. Production runs at 2000 kg/month, so small orders move fast.
