Over 99% purity is the headline number here, and what that actually means in practice is you're not chasing ghost peaks or weird baseline shifts during HPLC analysis — it's consistent batch to batch, which matters when you're running time-sensitive assays on cellular NAD+ depletion or sirtuin activity.
We've been shipping this to labs in teh US and EU for about 18 months now, and the biggest headache we solve is the import documentation — we include a full COA with HPLC trace and a TDS as standdard, so customs in the UK or Germany usually clears it in 2-3 days, give or take.
It's a, and one thing you'll notice right away is it reconstitutes cleanly in water or buffer at room temp — no sonication needed, no cloudy residue left behind — but you absolutely have to store the reconstituted solution at 2-8°C or you'll lose activity within a week or so.
Packaing comes in 100mg, 500mg, or 1000mg vials, and honestly most buyers go with the 500mg because it's enough for a decent dose-response curve without committing to a gram — the MOQ is one vial, so you're not locked into bulk if you're just validating a protocol.
One limitation worth flagging: this is not suited for cell culture work that requires sterile filtration without endotoxin testing — we don't guarantee endotoxin levels, so if that's your use case, you'll want to source a separate lot for that specifically.
CAS is 23111-00-4, molecular weight 663.43 g/mol, and the formula is C21H27N7O14P2 — the salt form is important here because of that it affects solubility; we're shippng free acid form, so if you need the sodium salt, that's a different SKU we'd need to confirm stock on.
