We've been supplying this for years to labs running metabolic and aging studies, and most buyers go with the 10g vial for smaller assays—it's easier to handle than the bulk drums.
Purity checks out at 99% or better by HPLC, and the white crystalline powder dissolves cleanly in water, which matters when you're prepping stock solutions at precise concentrations (usually 50mM or so).
CAS 53-84-9, molecular weight 324.89 g/mol—that's zwitterion form, not teh sodium salt, so it's better than reagent grade for enzymatic work where ion interference is a concern.
Storage is 2-8°C and protected form light; we've had customers leave it on the bench for a week and see no degradation, but don't push it—the powder is hygroscopic and will clump if exposed to humidity.
You'll get a COA with each batch, and our company can provide an SDS if needed, but the lead time is typically 2-4 weeks for orders under 500g.
Not ideal for cell culture work without buffering—the zwitterion can shift pH in unbuffered media, so check your system before scaling up.
Our MOQ is 1 gram per batch. For larger research quantities, we can scale up—just let us know your needs.
Orders are processed within 3-5 business days, depending on stock. Custom orders may take longer.
Yes, we provide a COA with every shipment, including HPLC purity data (≥99%) and other spec results.
That’s the molecular weight for the zwitterion form, which excludes counterions. The formula weight for the neutral compound is higher.
Store it at 2-8°C, protected from light. In those conditions, it stays stable for at least 12 months.
