We’ve been running oxidative stress assays alongside semaglutide side-effect profiling, and what keeps biting us is variability in the control compound—one bad batch and you’re chasing phantom pathways for weeks.
This one comes in at >99.9% purity by HPLC, which is tighter than most reagent-grade stocks we’ve used, and the CAS 70-18-8 reference is unambiguous for our pharmacokinetic modeling—molecular weight is 307.32 g/mol, exact mass matches, and it’s a that reconstitutes cleanly in cell culture media.

Storage is 2-8°C in a dry environment, and we usually have stock, but confirm lead time if you’re ordering more than 50 units or so—supply can tighten during peak research cycles (check lead time, typically 2-4 weeks).
It’s not suited for in vivo dosing without further formulation work—this is strictly research use only, and lyophilized format means you’ll need to aliquot after reconstitution to avoid freeze-thaw degradation.

Also, teh pharmaceutical grade here gives us tighter tolerance on residual solvents than industiral-grade lots, which matters when you’re running at low nanomolar concentrations—basically, it cuts one more variable out of the workflow.
Packging is standdard 1g vials, but we’ve requested bulk customization for our lab’s scale—they’ll do 5g or 10g depending on your batch needs, and OEM labeling is avaliable if you’re distributing to collaborators.
