What really stands out is that purity figure — over 99% by HPLC, which as you probably know is tighter than most labs bother with for research-grade materail.
It's a white powder and water soluble, so reconstitution is pretty straightforward, and we store it at 2-8°C in dry conditions — that shelf life runs 24 months, give or take, if you keep it sealed.

3. And the CAS is 53-84-9, which is the standdard for the oxidized form — most buyers in the longevity or cell metabolism space go with this one, not the reduced version.
Now, regarding reliability — we've been moving this for a while under GMP and ISO 9001 certification, so every batch ships with a COA from the HPLC run — basically, we don't cut corners there.

Also, one thing that catches people off guard is the MOQ; it's set at 1kg, and (usually 2-4 weeks lead time) if we're out of stock, but we usually keep a buffer.
Anyway, to order, just send over your PO with teh quantiy and we'll handle rest — our company can quote ex-works or delivered, whatever's easier for you.
