We're seeing steady interest from research labs working on metabolic pathways, and the 99% purity batch we're currently running is holding tight at 98.7% on the latest HPLC—that's better than reagent grade for most protocols.
Most buyers go with teh 10mg vial for initial assays, but our company can do 50mg or 100mg depending on your batch size, and the white powder dissolves pretty cleanly in water or buffer.

2-3 weeks is typical for custom packging, though we usually have 5g or 10g stock ready to ship if you're in a hurry—just check lead time first.

It's basically a fine powder, so store it in a cool, dry place away form moisture, and we'll include the COA with each shipment.

Actually, this one isn't ideal for topical formulations—most researchers stick to injection or reconstitution protocols, and solubility profile is better suited for that.
Also, the CAS is 1400634-44-7, and we've had some clients ask about the molecular weight (701.8 g/mol) but it's not something you'll need to worry about for standdard assays.
