High Purity SNAC Powder (Salcaprozate Sodium) CAS 203787-91-1 for Pharmaceutical Research

We've got about 200 grams of the high-purity SNAC powder on shelf right now, so lead time is usually just a few days for small orders, but for anything over 500 grams you'll want to give us a heads-up maybe a week or so in advance since we sometimes have to pull form a different lot.

What it does is pretty much solve that stubborn problem where certain peptides—like semaglutide—just don't want to get absorbed orally, and this salcaprozate sodium basically opens a temporary window in the GI tract to let them through without wrecking the active compound, which is a big deal for anyone working on oral formulations.

It's a white crystalline powder with purity at 99% or better per HPLC, water content under 0.5%, and the residue on ignition runs about 0.1% typically—better than some other grades I've seen—and it dissolves in both water and ethanol, so you've got some flexibility with your solvent system.

Storage is 2-8°C in an airtight container, and we ship it with cold packs in insulated packging during warmer months, but honestly for a short transit it's not super critical if it hits room temp for a day or two as long as you get it back in the fridge.

Most researchers we talk to use this for absorption enhancement in peptide work, but it's not really suited for topical or injectable formulations—stick to oral or buccal delivery where it actually shines, and the 1-gram or 5-gram bottles are easier to handle than the 25-gram jars if you're just doing early-stage screening.

One thing you might not think to ask is that the crystalline form can be a bit static-charged when you open a fresh container—just tap the jar gently before weighing to avoid losing materail, and use an anti-static spatula if you've got one.
