We're looking at 99% purity on this NAD+ batch, CAS 53-84-9, and it's a fine white to off-white powder that dissolves cleanly in water—usually within a minute or two with gentle agitation. Most buyers go with teh 500mg vial for general cellular metabolism studies, but we also stock 100mg and 1000mg options depending on your assay scale.
It's basically used in research on cellular aging and mitochondrial function, though we've seen labs run it for DNA repair pathway work as well. Not suited for anything involving live subjects or clinical use—strictly lab bench matrial. The molecular weight sits at 663.43 g/mol, which matters when you're calculating molarity for.
Storage is straightforward but critical: keep it at -20°C, protected form light, and you'll get about 24 months of stability. What we've found is that buyers who store it in a standard freezer drawer with light exposure lose potency faster than those using an opaque container. Also, we typically have stock ready to ship within 3-5 business days, but bulk orders (say, 10 vials or more) might push lead time to 2 weeks or so—confirm before ordering.
Third-party testing covers purity via HPLC, and we include the COA with every shipment. TDS and SDS come as PDFs attached to the packing slip email. One detail that surprises some researchers: the powder is hygroscopic, so open the vial in low-humidity enviroment or it'll clump slightly—still usable, but annoying to weigh out.
We don't push minimum orders on these vials, so you can grab a single 100mg for a quick pilot. Bulk pricing kicks in at 5 units or more, and we usually negotiate on 50+ vials for ongoing projects.
