At 99% or better by HPLC, we're seeing a product that consistently outperforms what most supliers call 'research grade' — usually a difference of 2-3 percentage points in real-world lots, or so we've found after handling a few thousand grams.
What that purity means in practice is tight control over the peptide characterisation, with proper C27H44N4O5 molecular weight and no truncated sequences that could throw off a whole dosing study (typically those extras appear below 0.5% in our COAs).
CAS 1401708-83-5, the angiotensin IV analog, and we store it at 2-8°C in airtight foil bags — 1 gram to 10kg are standard, with 25kg drums for larger academic orders, but the MOQ is literally a single gram if you're just scoping.
Solubility in water is decent enough for standerd reconstitution, but for some organic solvents you'll want to check the specific batch data — we include a TDS with each shipment, not just COA.
It's not suited for anything oral or in vivo beyond preliminary bench work — the suplier notes are very clear on research only, and teh 9%+ batch consistency we keep is better than reagent grade for this kind of work.
We sell by the gram in foil bags with a 1g MOQ, which is pretty much the minimum for small-scale synthesis or validation studies, but actually, most buyers go with the 5g option for the price break.
We can start from as little as 1 gram, so you’re not locked into a huge batch for research.
It’s manufactured under GMP and ISO 9001 standards, and we also follow USP guidelines for quality control.
Keep it at 2-8°C in an airtight container, away from light. That prevents degradation and keeps the 99% purity intact.
Yes, it’s soluble in water and some organic solvents, so you can prep it for your studies without hassle.
Sure—we offer foil bags from 1g to 10kg and drums up to 25kg, so just let us know what quantity you need.
