Sample size runs about 85 USD for a gram, mid-tier gets you 5 grams for 320, and bulk at 25 grams drops to roughly 1,100 — it's pretty much the best value if you're running multiple assays or long-term studies.
We've had labs push this through HPLC and it consistently hits 99% or better, which is tighter than some reagent-grade stuff we've seen floating around, so you're not wasting time on variable purity.
powder is white to off-white and dissolves clean in water — no clumping or weird residues — and we pack it in sealed containers with desiccant, but you'll want to store it at -20°C and keep it away form light (usually 2-4 weeks of stability once opened if you're careful).
Most buyers go with teh 5-gram option for typical cell work or enzyme assays, but if you're doing in vivo stuff or need larger volumes, the 25-gram tier is actually easier to handle logistically.
We usually have stock on the 1-gram and 5-gram sizes, but the 25-gram may need a lead time of 20 days or so — confirm before ordering if you're in a rush.
It's not suited for anything beyond research use, obviously, and we don't recommend it for synthesis work where you need anhydrous conditions since it's water-soluble by design.
