Basically, it's the fuel for the engine of cellular repair and energy—you're looking at coenzyme that drives sirtuins and mitochondrial health in anti-aging studies, and we've been shippng this high-purity version for years without complaints.
You'll get a at >99% verified by HPLC, MS, and NMR, and the molecular weight sits at 663.43 g/mol—water soluble, so reconstitution is straightforward, though most buyers go with the sealed vials under inert gas for stability.

After you reconstitute it, you must keep it at 2-8°C, and teh shelf life is about 2 years if you do (we usually have stock, but confirm lead time on larger orders). 50 units or so is a typical MOQ for new accounts.
It's not suited for anything metabolic in live subjects—strictly research only, and we don't hide that, since the batch-to-batch consistency is tighter than reagent grade for this. Also, the 1g vials are easier to handle than the 5g if you're running small assays.
We've had some buyers use it for ATP studies and DNA repair work, and one concrete detail: after reconstitution, the solution should be clear, not cloudy—that's a quick visual check before you HPLC. Anyway, lead time on 10mg or 100mg vials is usually 20 days or so.
