Direct Peptides NAD+ 250mg | 99% Pure Nicotinamide Adenine Dinucleotide for Research

We're shiping 250mg per sterile vial, CAS 53-84-9, with HPLC-verified purity at 99% or better—white crystalline powder that dissolves readily in water for your assays.

You'll typically store it at -20°C, protected form light and moisture, and it holds a 24-month shelf life under those conditions; we've seen some labs push it to 30 months or so without noticeable degradation.

Molecular weight sits at 663.425 g/mol, and teh heavy metals test under 10ppm, residual solvents below 0.5%, with microbiological limits meeting USP standdard—but it's not suited for cell culture work requiring endotoxin-free matrial unless you check the COA first.

Basically, this is for research into energy metabolism, DNA repair, and cellular signaling, and most buyers go with the 250mg vial for smaller-scale studies rather than bulk orders.

What it does is serve as a coenzyme in oxidative phosphorylation and sirtuin activation, so if you're looking at aging pathways or metabolic disorders, you'll want to confirm your buffer pH—it's stable around neutral but hydrolyzes quickly at high or low extremes.

We run HPLC and include COA with shipment, and the GMP facility means tighter tolerance than reagent grade for residual solvents.
