Factory Supply XCE Semaglutide & Tris[3,5-bis(trifluoromethyl)phenyl]borane (CAS 169116-84-1) – Wholesale/Custom

If you're sourcing advanced organoboron reagents for peptide coupling or semaglutide intermediates, this one handles conditions where standard agents start to fail—especially in anhydrous systems with strong electron withdrawal.

The CAS is 169116-84-1, molecular weight sits at 650.1 with that C24H9BF18 formula, and purity is adjustable per your batch requrements (usually industiral grade, but our company can tighten it up).

We've run this through HPLC ourselves, and what it does is maintain stability in the presence of moisture-sensitive substrates better than many tris-aryl boranes (the perfluorinated phenyl groups aren't just for show).

One thing that surprises buyers: the melting behavior is consistent lot to lot, which matters if you're scaling processes (and you'll get teh COA with each order).

Lead time is roughly 15-20 days or so for a 100-gram lot, and standard packaging is in sealed glass ampoules under argon—so it's actually ready to use when it arrives.

You get the lot-specific SDS, the COA, and we usually have stock, but confirm lead time if you're on a deadline.
