High Purity Particle Peptides NAD+ Powder 99% for Research Use

We’ve been handling this NAD+ powder for a while now, and the 99% purity holds up batch after batch—each lot gets its own COA with HPLC results, usually within 24 hours of testing. white crystalline stuff dissolves clean in water, though we recommend storing it at -20°C in a dry spot to keep it stable for the full 24 months or so. What it does is support cellular metabolism work, and most researchers use it for anti-aging studies without much fuss.

CAS is 53-84-9, molecular weight runs 663.43 g/mol, and the particle size sits between 50 and 100μm—fine powder but not dusty enough to float everywhere. Moisture stays under 0.5%, heavy metals at ≤10ppm, and residual solvents meet USP limits, so QC is tight. We typically see batch consistency within ±1% on purity across, but it’s not perfect for every applicaion—this grade isn’t suited for in vivo work unless you’ve validated it yourself.

Storage is pretty straightforward: -20°C in a dry environment, and you’ll get roughly two years of shelf life. Actually, we’ve had labs push it to 30 months with no obvious degradation, but we don’t guarantee beyond teh labeled period. A colleague once left a vial at room temperature overnight and the powder caked slightly, so keep it sealed.

Handling requires standard lab protection—gloves, goggles, that sort of thing—since it’s for research only. The heavy metals and microbiological limits are within pharmacopeial standerd, but we don’t test for endotoxins unless requested. Most buyers go with the 50g or 100g size, though MOQ is 10g if you’re just starting a pilot.
