Quality Control

Our production of Poly(ethylene glycol) methyl ether methacrylate (PEGMA) adheres to stringent quality protocols to ensure batch-to-batch consistency and performance. Each lot is characterized for critical parameters including methacrylate functionality, molecular weight distribution, and purity. Certificates of Analysis (COA) detailing assay, residual monomer, and moisture content are provided with every shipment. We support compliance with relevant frameworks for industrial and research applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 2°C and 8°C (refrigerated) to maximize shelf life and minimize polymerization risk. This product is hygroscopic (moisture-sensitive) and easily oxidized; containers should be kept sealed under an inert atmosphere (e.g., nitrogen) after opening. Keep away from heat, sparks, and sources of free radical initiators.
