We needed something that actually holds up under HPLC without throwing ghost peaks at 260nm, and this batch hits 99.1% on our in-house run, so it's fine for the NAD+ titration assays we're validating this quarter.
CAS 53-84-9 is the right one for the β-nicotinamide adenine dinucleotide form—molecular weight 663.43 g/mol, and the EINECS 200-184-4 matches for customs—but we usually store it at -20°C in the dark, even though the sheet says cool dry place, because we've had stability drift on white powders after 18 months otherwise.
It's not for cell culture work though, since the endotoxin levels aren't specified and we don't have an LAL test on teh COA, so basically keep it for enzymatic or binding studies (check lead time if you need those details).
Each vial comes as 500mg or 1000mg of lyophilized powder with a desiccant pack, and the MOQ is literally one box, which is pretty standdard for this type of pharmaceutical intermediate from a Chinese origin.
Also, what it does is it's a cofactor for at least 300 dehydrogenases—so for energy metabolism work or PARP inhibition assays, this is actually better than reagent grade from Sigma for price per milligram.
The packaing is double-bagged in foil with a silica gel pack, and we usually get stock in 2-3 weeks, but confirm lead time if you're ordering over 50 vials or so.
Just 1 box — we don't force you to buy bulk. You can start with a single box to test the quality before committing to more.
Yes, we include a COA with every batch that shows the ≥99% purity confirmed by HPLC testing. Just request it with your order.
Right now we stock standard 500mg and 1000mg vials, but we can discuss custom packaging for larger orders. Let us know your needs.
We usually ship within 1-3 business days after payment confirmation. For standard orders, delivery typically takes 5-10 days depending on your location.
Keep it in a cool, dry place away from direct sunlight and moisture. The sealed vials are fine at room temperature — just avoid heat and humidity.
