LIANYUNGANG RUNHOU INT'L CO.,LTD offers polymer-grade Trimesoyl Chloride (TMC, CAS 4422-95-1) with a certified purity of ≥99.5%, specifically synthesized as an acyl chloride monomer for interfacial polymerization. Our TMC features ultra-low trace hydrolytic impurities (free trimesic acid ≤0.1%), making it the premier choice for manufacturing high-flux, high-salt-rejection Thin-Film Composite (TFC) Reverse Osmosis (RO) and Nanofiltration (NF) membranes.

### Core Applications

* **RO Membrane Manufacturing:** Active monomer for forming the polyamide skin layer in seawater desalination and brackish water membranes.

* **Nanofiltration (NF):** Matrix monomer for selective ion separation membrane synthesis.

* **Aramid Fibers:** High-strength polymer synthesis and chemical intermediates.

we provide a comprehensive technical dossier, including high-resolution FTIR/GC-MS spectra, trace impurity analysis, and global GHS-compliant SDS
