white powder arrives in those 2mg vials we've been using for the past few months, and purity consistently runs at 99% or better per the COA — it's pretty much what you'd expect form a solid suplier. We usually have stock, but confirm lead time if you need more than 50 units or so.
Most buyers go with this for their lab work, not for anything clinical or human use obviously, and teh CAS number is 859216-15-2 if you're cross-referencing. Storage is straightforward: 0-4°C for the short haul or -20°C if you're holding it longer than 20 days or so, and we've found the shelf life easily exceeds two years when kept properly.
It's not ideal for large-scale synthesis work because the vial size is small, but for targeted peptide studies it's better than reagent grade for this. One thing buyers don't always ask but should: avoid repeated freeze-thaw cycles or you'll lose activity quicker than expected.
And the HS code is 2934.99.9001 if customs needs it. Actually, we've seen some researchers use it for metabolic pathway work, and the 2mg format is easier to handle than bulk powder when you're doing multiple assays.
We typically require a minimum order of 10 vials for this product, but we can discuss smaller quantities for first-time buyers or lab trials.
Standard lead time is 5-7 business days for processing, plus shipping time to the UK which usually takes 3-5 business days via express courier.
Yes, we supply a COA with every batch showing ≥99% purity confirmed by HPLC, and we can also share third-party test results upon request.
Store them at 0-4°C in a fridge for short-term use, or at -20°C in a freezer for long-term storage. Properly stored, they stay stable for over 2 years.
Each 2mg vial is nitrogen-purged and vacuum-sealed to protect the white powder from moisture and oxidation during transit and storage.
