So you're looking at NAD+ powder for bulk—we're shippng it as a white, free-flowing powder that's pretty much teh go-to for metabolic pathway work, with a purity pushing past 99% verified by HPLC.
It's electron shuttle that powers ATP production through oxidative phosphorylation and also feeds sirtuin activity for those protein deacetylation studies, but you'll want to keep it at -20°C or so to maintain stability.

We usually have stock on the 500mg and 1000mg vials—give or take a few days for larger MOQs though, solubility hits 50 mg/mL in water easy, and the CAS is 53-84-9 if you're cross-checking vendor lists.

One thing you don't see on spec sheets is that this batch handles freeze-thaw better than most—we've tested it down to three cycles without significant degradation, which is rare for a peptide.

Actually, this isn't something you'd use for cell culture additives since it's strictly research-use only and the phosphate groups can interfere with some buffers if you're not careful.
We also include the COA with every order and can send full TDS or SDS on request.
