A buyer's custmer running a metabolic study on 3T3-L1 adipocytes will dissolve this in sterile water at 5mM stock, then aliquot and freeze at -80°C for up to three months — just make sure to avoid freeze-thaw cycles. We've seen researchers get clean dose-response data at 100-500µM range when paired with resveratrol. It's water soluble so no DMSO worries. Basically, if you're looking at NAD+ rescue in senescent cell models, this is what you want.
Purity runs >99% by HPLC with MS verification, and we routinely see 99.3-99.5% on the COA. The CAS is 53-84-9, MW 663.43 g/mol, and it's a white to faintly yellow powder that holds steady at 2-8°C in sealed vials with desiccant — shelf life is 24 months if stored properly. Most buyers go with teh 500mg vial because of that it's easier to handle than the 100mg option for repeated studies.
1.189 g/mL density at 25°C, melting point over 300°C, flash point above 230°F — but honestly, you're not heating this up for any applicaion. It's research grade only, not suited for anything in vivo or clinical. We usually have stock, but confirm lead time if you need more than 50 vials. Also, the refractive index is n20/D 1.452 if that matters for your formulation work.
One thing buyers don't always think to ask: the powder is hygroscopic, so after opening, use it within a few hours or store under argon — otherwise you'll see a slight yellow shift over weeks. We've had a few labs complain about caking, but that's poor handling, not product. Tighter tolerance than most generic NAD+ sources on residual solvents.
