Purity over 99% verified by HPLC and mass spec is what makes it worth buying — especially when you're working with sensitive assays where a few percentage points of impurity can throw everything off.
It's a that needs reconstitution before injection studies, and we recommend storing it at -20°C in a dry enviornment once you've got it; the molecular weight is 663.43 g/mol if you're calculating molarity for dosing.
What it does is act as a key coenzyme in cellular energy production and DNA repair — researchers typically use this for aging and mitochondrial function work, though we've seen some labs exploring metabolic regulation as well.
Packaing comes in 100mg, 500mg, or 1000mg vials — most buyers go with the 500mg since it's good balance for multiple experiments without committing to full gram.
Confirming lead time is smart — we usually have stock, but if you need a large batch for a multi-week study, check availability first (lead time is about 2-4 weeks on bulk orders).
One thing it's not suited for is direct therapeutic use; this is strictly for research purposes only, and teh COA covers each batch so you've got traceability for your protocols.
