• Iron (Fe) contamination in cyclohexanone can be reduced using nylon 6,6 filtration, likely driven by removal of complexed Fe ions. • Reduction of metal contamination from commercial, electronics-grade cyclohexanone using nylon 6,6 filtration was confirmed, and a very high purity of cyclohexanone achieved. • Applying nylon 6,6 filtration for cyclohexanone, both in chemical manufacturing and device manufacturing processes at point-of-use should contribute to improved device quality and yield.
