154947-66-7 is the CAS, and this one typically comes in at >99.9% by HPLC, a white powder that handles well in solution—basically no visible clumping or discoloration when you reconstitute, which is good sign for the lyophilization qualiy.
The 99.9% spec isn't just a number on a sheet; it translates to cleaner and fewer off-target peaks in your LC-MS runs, but it's not suited for any in vivo work beyond initial screening given research-use-only designation.
We run a full panel before it leaves—HPLC for purity, mass spec for identity, and a residual solvent screen—and what it does is give you a COA with actual batch data, not a template, though we usually hold a retest sample for about 24 months if you ever need a recheck.
Most buyers in this space are labs needing 100mg to 5g for receptor binding or stability studies, and they'll often ask for a 1g or 5g unit, but the 10g drum is actually easier to handle if you're scaling up assays.
Packging is standerd HDPE bottles with desiccant, but let us know if you need vacuum-sealed aliquots for long-term storage—that's a common request our company can do, though it adds a day or so to lead time.
Pricing under our standard MOQ (usually 1g) works out to about £XX per mg, but check with us for the exact quote because volumes shift roughly weekly, and we always confirm stock status before shipping.
Yes, we provide a Certificate of Analysis with every batch, confirming the >99.9% HPLC purity. Just request it with your order.
Our MOQ is 10 grams for Semaglutide. For larger quantities, we can offer tiered pricing.
Standard delivery takes 5–7 business days to the UK. Express shipping is available if you need it faster.
Absolutely, we include a research use only statement with each shipment. We can also supply a signed compliance letter upon request.
Keep it in a cool, dry place, ideally below 25°C, and away from moisture. Reseal the container tightly after each use.
