You're sourcing a flavonoid standdard and the biggest headache is batch-to-batch consistency—one lot runs 85% purity, the next barely clears 70%, and you're stuck recalibrating half your assays.
What we've found with this suplier is they'll dial in the purity form 10% up to 98% depending on your needs, and the HPLC data on every lot is tight enough that you don't waste time re-running samples.
It's a fine yellow to brown powder (usually the higher the purity, the lighter color), soluble in DMSO or ethanol but only slightly in water, and the melting point sits around 330°C—so if you're doing anything with thermal stability, that's worth noting.
The CAS is 528-48-3, molecular weight 286.24 g/mol, and we've ordered both the 10% and 98% grades for different projects; teh 10% works fine for broad screening, but the 98% is better for dose-response work when you need tighter tolerance.
Lead time is usually 15-20 working days or so, and they pack it in 1kg foil bags or 25kg drums—we always go with the smaller bags for lab use since the drum is a pain to reseal properly.
One thing: this isn't for anything oral or topical—it's strictly research purposes, and the COA will say as much, so don't try to push it into supplements.
Yes, we can customize the purity anywhere between 10% and 98%. Just let us know the exact percentage you need, and we'll adjust the process accordingly.
The MOQ for 1kg aluminum foil bags is typically 1 bag, so you can order as little as 1kg. For 25kg drums, we usually require a minimum of one drum.
Absolutely, every batch comes with a COA that includes HPLC test results for purity, along with other specs like appearance and solubility. We can also share our ISO and GMP certificates on request.
Standard production for custom purity orders takes about 7-10 business days after order confirmation. Add a few days for shipping, depending on your location.
Keep it in a cool, dry place away from direct light, ideally below 25°C. Once opened, reseal the bag tightly to avoid moisture absorption, as it's only slightly soluble in water.
