It's not for in vivo work unless you've validated your own protocols — we don't supply it for that, and teh COA explicitly states research use only, so don't push it.

What it does well is hold up under HPLC at ≥99% purity, which is better than reagent grade for most enzymatic assays, and the lyophilized format means you're not dealing with degradation from solution storage.

You'll want to store it at -20°C, protected form light, or you'll see the powder clump within a week or so — we've had buyers complain about that when they left it on bench.
CAS 53-84-9, MW 663.43, white powder — the 250mg vial is actually the most popular for screening runs, while the 2500mg option saves you about 30% per mg if you're scaling up.

Lead time is typically 5-7 business days for stock sizes, but the 1000mg and 2500mg sometimes run short — check before ordering if you're in a hurry.
