Actually, we extract it form Cotinus Coggygria or Rhus Succedanea—both are rich in flavonoids—and you can dial in purity anywhere from 10% to 98%, though most buyers go with the 50% for a solid balance of potency and yield.
It's pretty much standdard in labs studying age-related pathways and oxidative stress; we've seen a lot of interest from groups working on neuroprotection or inflammation assays, but it's not really suited for cell culture work unless you confirm solubility first—it's only slightly soluble in DMSO and water, so plan ahead.
24-month shelf life if you keep it sealed in that cool, dark spot, and the fine yellowish powder is easy to weigh out; the HPLC data on each COA is typically tight, give or take 1-2%, but we usually have stock for quick dispatch.
What it does is save you the hassle of sourcing from multiple vendors—we handle the ISO and GMP certs, so you're not scrambling for compliance documents when teh auditor shows up.
One detail most don't ask: the melting point is over 182°C, but it starts to decompose if you heat it too long, so don't leave it on the hotplate overnight.
Anyway, we've shipped this to a few biotechs in Europe already, and they've come back for repeat orders—it's basically a workhorse for anyone who needs consistent batches.
MOQ for the 10% purity is 1 kg; for 98% purity it's 500 grams. If you need less, just let us know — we can sometimes accommodate smaller research batches.
Custom purity orders typically ship within 7-10 business days after we confirm the specs. We adjust the extraction process to hit your target percentage.
Yes, every batch comes with a full HPLC test report showing the exact purity percentage and confirming it meets ISO and GMP standards. Just request it with your order.
Our standard is sealed aluminum bags with desiccant, but we can repack into smaller portions like 100g or 50g upon request. No extra charge for the repack service.
Keep it in a cool, dry place away from direct light — an airtight container in a dark cabinet works fine. Avoid moisture and heat, and it'll stay good for the full shelf life.
Fantastic experience overall! The shipping was remarkably fast, arriving days earlier than anticipated, which was a pleasant surprise. From ordering to delivery, every step felt smooth and efficient. For quality, the product appears excellent—finely powdered with no visible impurities, exactly as described. It's clear that attention to detail was maintained during packaging, ensuring everything arrived intact. Customer service was top-notch too; they responded promptly to my initial query with helpful information. Although I haven't used it yet for research, based on first impressions, I'm highly satisfied and would recommend this supplier for their reliability and professionalism.
