We've been handling this batch for a while now, and the 99% HPLC purity holds up consistently across vials — it's better than reagent grade for most in vivo work.
CAS 121062-08-6 with the C50H69N15O9 molecular formula, white powder that's soluble in DMSO but not something you'd just toss into saline without checking solubility first. 5mg or 10mg per vial depending on your protocol, and we usually have stock in 10-vial boxes. Most buyers go with teh 10mg for repeated dosing, but the 5mg is fine if you're testing low concentrations. Storage at 2-8°C in a dry enviornment is critical — leave it out at room temp for a week and you'll degrade it (we've seen that happen). 24-month shelf life when properly stored, but confirm lead time if you're ordering bulk because we sometimes run short on 10mg.
Not suited for anything beyond research use — it's strictly an α-MSH analog for lab applications, so don't expect it to work in cell-free systems. One thing you might not think to ask: vials have a slight vacuum seal, so pop them carefully to avoid powder loss.
Packging is straightforward: 10, each vial individually sealed, and we include a COA with every order. The 5mg vials are easier to handle for small-scale work, but the 10mg gives you more flexibility.
Basically, if you need a tight tolerance on purity and consistent batch-to-batch data, this holds up. We usually have about 50 units or so in stock, but check lead time for anything over 100 vials.
Yes, we provide a Certificate of Analysis with every batch. It shows the actual HPLC purity result so you can verify the ≥99% spec yourself.
Our standard MOQ is one box of 10 vials, either 5mg or 10mg per vial. We don't break boxes, so you'd need to order at least 10 vials per spec.
Lead time is typically 3-5 business days for stock orders. If we need to manufacture a fresh batch, it can run 10-14 days — we'll confirm when you order.
Short exposure to room temp during transit is fine, but once you receive it, store it at 2-8°C in a dry place. Extended time outside that range can degrade the powder and shorten the shelf life.
It's raw pharmaceutical intermediate powder, not sterile. For research use only, you'd reconstitute it with a sterile solvent like bacteriostatic water before any lab work.
