A 4813 molecular weight compound with that CAS number—2023788-19-2—hits a specific spot in teh peptide field, and we've been shiping it as lyophilized powder in 5mg, 10mg, or 20mg (10 vials) for a while now; it's pretty much the standdard format for reconstitution work.
You're looking at 99% purity by HPLC, which matters because even a fraction of a percent off can shift results in sensitive assays, and the pharmaceutical grade designation means tighter tolerances than reagent grade—but don't take our word for it without checking the COA first, usually 2-4 weeks lead time for those.
Basically, if your lab runs or stability studies, this form holds up better than a pre-mixed solution (we've seen degradation in liquid after a year even refrigerated), so lyophilized state gives you about 2 years shelf life in a cool, dry place.
Most buyers go with the 10mg vial for convenience, but the 5mg is easier to handle for small batches—though it's not ideal for high-throughput screening where you'd want larger volumes anyway.
Also, we usually have stock on the common sizes, but confirm lead time for the 20mg vials since they move slower and might need a production run of 50 units or so.
An odd one: some folks don't realize the powder can clump if exposed to humidity during reconstitution, so keep that desiccant handy—it's a small detail that saves a batch.
The MOQ is 10 vials per box, so you'd need to order at least one full box of the 10mg/vial size.
We usually ship within 3-5 business days after order confirmation, depending on stock levels.
Yes, we include a CoA with every batch, verifying the 99% purity and other specs like molecular weight.
Keep it in a cool, dry place away from direct sunlight, and it'll stay good for the full 2-year shelf life.
We can adjust box quantities for larger orders, but standard is 10 vials per box for each size.
