Roughly 4119.6 Da molecular weight on this one, and it's a white freeze-dried powder that's been HPLC verified at 99% purity or better — we run the MS alongside HPLC. 2. Most buyers go with the 10mg vial for dosing flexibility, though the 2mg and 5mg options are there if you're running low-concentration work or just starting out. 3. It's not suited for anything beyond lab research, obviously, and the -20°C storage is non-negotiable — skip that and you'll lose stability fast, usually within a week or so at room temp. 4. We're ISO9001 certified, so every batch has a COA that covers both purity and identity, and we typically stock teh 10-vial boxes (2mg, 5mg, or 10mg per vial) but custom quantities are possible if you confirm lead time. 5. It basically dissolves in water or sterile bacteriostatic water without much fuss, and the 36-month shelf life holds if you keep it dry and frozen — one thing most people don't ask is that the powder can clump if the vial warms up during reconstitution, so let it come to room temp slowly. 6. Anyway, the 5mg vial is easier to handle for single-use reconstitution than the 2mg, and we've seen fewer complaints about residual moisture with that format.

We can do as little as 1 box (10 vials) for a single strength, but if you need mixed strengths in one order, just ask. MOQ really depends on your specific needs, so reach out and we'll work it out.
Absolutely. Every batch comes with a COA that includes HPLC and MS data, so you can verify the ≥99% purity yourself. Just let us know if you need it before shipping.
Keep it at -20°C in a dry place, and it'll stay stable for up to 36 months. Once you reconstitute it, use it right away or store it per your protocol—just avoid freeze-thaw cycles.
For stock sizes like 2mg, 5mg, or 10mg per vial, we usually ship within 3–5 business days. Larger custom orders might take a bit longer, but we'll give you a firm timeline upfront.
We can customize the box label and vial count for bulk orders, but the standard 10 vials per box applies unless discussed. Just specify your needs when ordering, and we'll see what we can do.
