High Purity NAD+ Powder CAS 53-84-9 | 99% Nicotinamide Adenine Dinucleotide Supplement

The real headache we kept running into was inconsistent NAD+ qualiy—some batches would degrade before we could even use them, and others had purity claims that didn't hold up under HPLC.

What we've got here is a 99% pure powder that actually holds stable at -20°C for a solid 24 months or so, and we've never seen it yellow or clump even after long-term storage.

You're looking at a white to off-white crystalline powder, soluble in water, with an absorption max at 260 nm for teh oxidized form—this is research grade, not for human use, and it's better than reagent grade for metabolic studies where you need tight tolerance on the electron carrier side.

It basically handles the redox reaction work in glycolysis and the citric acid cycle without variability we used to see form other suppilers.

Stock is usually availble, but we do check lead time (typically 2-4 weeks) before we commit—MOQ is 5 grams, and it ships in a sealed foil pouch with a desiccant pack.

Also, one thing you might not think to ask: the powder is hygroscopic, so we recommend opening it in a dry environment or under inert gas if you're splitting batches.
