PGMEA Electronic G1 Grade
CH₃COOCH(CH₃)CH₂OCH₃ · CAS 108-65-6
G1 grade PGMEA for I-line (365nm) and G-line (436nm) positive photoresist formulations in mature node fabs, TFT-LCD array lithography, and PCB dry film photoresist processes. Cost-effective alternative to G4/G5 where EUV/ArF purity is not required.
