High Purity Lifetech Peptides Palmitoyl Tetrapeptide-7 CAS 221227-05-0 for Research

our company can do custom vial sizes and labeling if you need them, plus bulk synthesis is an option for larger runs, so just specify concentration or format you're after — we usually have stock, but confirm lead time (check on custom orders, they add a week or so). Basically, it’s the Palmitoyl Tetrapeptide-7 at ≥99% purity, white to off-white powder that’s soluble in both water and ethanol, so it handles fine in most research buffers.

CAS is 221227-05-0, molecular weight 673.91 g/mol, and it’s stored at -20°C in a dry enviornment — skip that and you’ll see degradation within months, not the 24-month shelf life it should have. Most buyers go with sealed vials with desiccant, which is how we ship it anyway, and teh typical use is dermatological studies or cosmetic research, not for ingesting or anything like that.

24 months of shelf life, but that assumes you don’t open and close the vial a hundred times; for a single-use lab, it’s fine. We run HPLC and MS on each batch and provide a COA — nothing fancy, just the numbers you’d check for purity and identity, and it’s better than reagent grade for this kind of work.

Actually, one thing: this isn’t suited for oral bioavailability studies or in vivo work without further formulation, as the tetrapeptide is pretty much designed for topical or cell-based assays, so plan accordingly. A concrete detail form handling it: the powder can be slightly hygroscopic if left out, so reconstitute quickly after opening.

10mg, 50mg, or bulk — we can label it as you need, and the price shifts with volume, roughly 20-30% off for orders over 100 vials or so. No call-to-action here, just what thing does and how it ships.
