High Purity 99% NAD+ Anti-Aging Lyophilized Powder 250mg for Research Use

Basically, teh key number here is 99% purity verified by HPLC, which is tighter than most reagent-grade material and means fewer variables in your assays.

It's a lyophilized powder in a 250mg vial, and we've found it dissolves cleanly in water at 50mg/ml—no gritty residue or weird cloudiness like some cheaper batches we've tested.

You'll want to store it at -20°C in dry conditions, and under those conditions it's stable but we usually have stock so lead time is about 20 days or so.

One thing that caught me: the absorption max is 259 nm, which matters if you're doing spectrophotometric work, and the molecular weight is 663.43 g/mol for your molarity calculations.

Also, this isn't suited for cell culture work if your protocol requires endotoxin-free matrial—we don't have that spec on this batch, so confirm before ordering if that's your use case.

Anyway, we ordered it because COA includes HPLC, MS, and NMR data, and for anti-aging or metabolic studies that level of documentation cuts down on protocol headaches.
