That >99% purity number isn’t just a spec sheet filler—it actually means fewer side reactions in your metabolic studies, which saves you weeks of re-running assays with lower-grade stuff.
You’ll get that white crystalline powder with a tight melting point of 140-142°C, so you know batch consistency is solid before you even open teh vial.
Storing it at 2-8°C in a dry cabinet keeps it stable for a full 24 months, which is better than some supliers who give you six months max.
Honestly, most labs we talk to waste time chasing NMN or NR when NAD+ is the direct substrate for the enzymes they’re actually studying—no conversion steps, no extra variables.
CAS 53-84-9 number lets you cross-reference every shipment against your own documentation, and the HS code 2907191000 clears customs without the usual delay.
Order it as a research chemicla only, handle it with proper lab gloves and a fume hood, and it’ll keep for two years without losing activity if you follow that 2-8°C rule.
