About
A specialty supplier built on chemistry
Meridian Chemical Solutions LLC is a US-based supplier of amine and imidazolium chemistries for carbon capture, water treatment, and industrial recovery processes.
Meridian Chemical Solutions LLC is an early-stage specialty chemicals company supplying amine and imidazolium chemistries to industrial customers in the United States.
Our portfolio covers five product lines: polyethyleneimine (PEI) across a molecular-weight range of 600 to 100,000 g/mol, polypropyleneimine (PPI) for higher amine density, imidazolium ionic liquids, phenol-selective adsorption resins, and finished CO₂ sorbent formulations. The same amine chemistry runs through all of them — it binds CO₂ in capture systems, chelates metals and flocculates solids in water treatment, and recovers phenol from process streams that would otherwise be treated as waste.
We work with qualified manufacturing partners, with lot traceability from raw material to shipment. Every product ships with a certificate of analysis, and SDS and technical data sheets are available for the full range.
We supply from kilogram evaluation samples through to commercial volumes, and we expect to earn each order: samples first, then technical qualification against your process, then supply.

What we stand for
Reliability
Consistent quality across every lot. When a customer qualifies a Meridian product, they can rely on the same specification, the same CoA format, and the same delivery commitment for every order that follows.
Technical Depth
We are chemists first. Our technical team can discuss structure-property relationships, help interpret analytical data, and co-develop specifications — not just process purchase orders.
Responsibility
We take our responsibilities seriously: to the safety of the people who handle our products, to the regulatory frameworks in the markets we supply, and to the environmental impact of the processes our chemistry is part of.
