Straight away, let's address the big one — we see a lot of people worried about purity dropping off after shipment, and with this batch you're looking at 99% verified by HPLC, consistently well above the 98% threshold most researchers find acceptable for sirtuin activation work or PARP inhibition studies.
What it basically does is shuttle electrons in those key redox cycles, form glycolysis through to oxidative phosphorylation, but teh real challenge we often hear about is keeping the powder stable once reconstituted, which is why we ship it lyophilized and insist on -20°C storage with minimal light exposure — it holds for three years that way, give or take.
That CAS 606-68-8 number leads to a sodium salt form at about 663 grams per mole, and yeah, melting point is around 140-142°C, but honestly most of you aren't melting it; what matters more is that 50 mg/mL solubility in water means you can prepare stock solutions pretty easily without fighting precipitation.
One thing buyers don't always think to ask about is that specific rotation of -31.5° at D20 — it’s a small detail but it flags whether you’ve got the natural beta-anomer or any racemic contamination, so we include the polarimetry data on every COA just for that reason.
We’re not kidding ourselves, it’s not suited for long-term oral dosing work or anything where you’d need buffered saline stability past a week; this is really for your acute cell culture assays or ex-vivo enzyme kinetics where you control for redox state — any quantitative PCR or NAD/NADH ratio experiments in the lab are where it shines.
For the MOQ we usually have 1-gram and 5-gram vials in stock, and if you’re doing serial dilutions for a time course, the 5-gram drum is easier to handle than ten tiny vials; our company can ship GMP-grade with the USP or BP cert at no extra charge, lead time is about 20 days or so depending on where you are.
We can start with as low as 1 gram for research orders, but bulk discounts kick in at 10 grams or more. Just let us know your required quantity.
Typically 5-7 business days for standard orders, but if you need it faster, we can arrange expedited shipping within 2-3 days. We'll confirm the timeline when you order.
Yes, we include a COA with every batch showing ≥99% purity, specific rotation, and other specs. You'll also get access to our GMP and ISO 9001 certifications on request.
It dissolves at 50 mg/mL in water, so for a typical 100 mg vial, just add 2 mL of sterile water. Use it immediately or store at -20°C and protect from light to keep it stable.
We offer it in sealed vials for smaller quantities (1g, 5g) and foil bags for larger amounts. All packaging is light-protected and suitable for -20°C storage, with a 3-year shelf life when stored correctly.
