4731.33 g/mol is the molecular weight, which puts it in that tricky middle zone for handling — not a small molecule you can just throw around, but not quite a full protein either, so it needs careful reconstitution most buyers go with buffered solutions rather than plain water.
We ordered this because our usual semaglutide suppiler had a three-month lead time and we needed something within 20 days or so, and this batch tested at 99.2% by HPLC so it's actually tighter than teh minimum spec.
The lyophilized powder comes as a white cake in 10mg or 20mg vials, and one thing you don't always think about is that it's hygroscopic so you'll want to bring the vials to room temp before opening otherwise you'll get condensation inside — we usually keep a dessicator in the fridge for this.
It's a GLP-1 agonist but specifically the semaglutide analogue sequence, so it's not ideal for acute signaling studies where you need the native GLP-1(7-36)amide backbone, but for metabolic stability work or long-term dosing protocols it's actually better than reagent grade for this.
Storage is 2-8°C and dry, which is standdard for any lyophilized peptide, but CAS is 2381089-83-2 so make sure your internal tracking system recognizes that variant because some older databases still list the older semaglutide forms under different numbers.
Also, the MOQ form this supplier was only 5 vials so that worked for our pilot batch, but they mentioned larger quantities take 2-3 weeks extra for production scheduling.
We can do as little as 10mg per vial for research orders, but if you're running larger studies, let us know your volume and we'll work out bulk pricing.
Yes, every batch comes with a detailed HPLC certificate of analysis showing purity ≥99%, so you can verify the specs before using it in your research.
Keep it in the original vial at 2-8°C in a dry place—don't freeze it. Make sure it's sealed tight to avoid moisture, since it's lyophilized and sensitive.
For research orders we usually stick to 10mg and 20mg vials, but if you need a different size for a specific protocol, just ask—we can sometimes accommodate custom fills.
We usually ship within 1-3 business days after order confirmation, depending on stock. International orders may take a bit longer due to customs clearance.
