NAD+ (Nicotinamide Adenine Dinucleotide)

Lyophilized powder · 500mg vial · 99.1% purity by HPLC · CAS 53-84-9

What is NAD+ and why do researchers use it?

NAD+ is a coenzyme found in every living cell. Its full name is nicotinamide adenine dinucleotide. It plays a central role in cellular energy metabolism. So it shows up in a huge range of biochemical research.

Also, NAD+ is a key substrate for enzymes like sirtuins and PARPs. These enzymes are studied in aging research, DNA repair, and metabolic biology. That makes NAD+ one of the most referenced compounds in cell biology labs.

However, NAD+ is sold strictly for in vitro and laboratory research. It is not for human use.

Is this NAD+ tested for purity?

Yes. Every batch is tested by HPLC before it ships. Our NAD+ reaches ≥99.1% purity. That result is backed by a certificate of analysis (COA).

First, the raw material is tested at synthesis. Next, a third-party lab runs a second HPLC confirmation. Finally, the COA is attached to your order. You can also download it directly from this page.

Therefore, you know exactly what you are working with before you open the vial.

What is the molecular formula and structure of NAD+?

The molecular formula is C₂₁H₂₇N₇O₁₄P₂. The molecular weight is 663.43 g/mol. NAD+ consists of two nucleotides joined by a phosphate bridge. One side carries adenine. The other carries nicotinamide.

But the structure is not just academic. The nicotinamide ring is the active site. It accepts and donates electrons during redox reactions. So understanding the structure helps researchers design meaningful assays.

How should NAD+ be stored to stay stable?

Store lyophilized NAD+ at -20°C in a dry environment. Avoid repeated freeze-thaw cycles. Also, keep it away from light and moisture. These degrade the compound faster than temperature alone.

Once reconstituted, use the solution within 24 hours or aliquot and refreeze. However, do not refreeze more than once. Stability drops each time.

Our vials are vacuum-sealed and shipped with desiccant. So shelf life under proper storage is at least 24 months from manufacture date.

What vial sizes are available for NAD+?

We also stock NAD+ in 100mg, 250mg, and 500mg vials. All are lyophilized powder. Larger sizes are available for bulk orders. Contact us directly for quotes above 1g.

Also, all sizes come with the same COA and purity standard. There is no difference in quality between vial sizes.
