We've been shipping this for years to labs and supplement formulators — the 99% purity holds up consistently batch to batch, and the 200 mesh means it dissolves faster in water-based formulations than coarser grades, which most buyers don't realize until they try it.
CAS 6020-87-7 is the monohydrate form, so you're getting C4H9N3O2·H2O with loss on drying under 12% — basically, it's stable for 2 years if stored dry, and heavy metals stay under 5ppm, which is tighter than the typical 10ppm limit for research use.
MOQ is 25kg per order, and we usually have stock in 20 days or so — check lead time though, because custom mesh sizes or packaing (like 1kg bags instead of 25kg drums) can add a week or so.
Payment is typically T/T or L/C at sight for first orders, and we send COA with HPLC data before shiping — for repeat clients, we can do net 30 after a few rounds.
It's not suited for injectable research without further purification, but for oral dosing or cell culture work, this grade works fine — just confirm your application before ordering because returns on custom-packed materail are tricky.
Also, we don't recommend using it in anything that requires USP-grade specs — this is research-use only, so documentation (SDS, COA) reflects that, and we don't provide cGMP certifcates for it.
