IPA Electronic G1 Grade
(CH₃)₂CHOH · CAS 67-63-0
G1 electronic grade IPA for mature-node PCB fabrication, display glass substrate cleaning, solar cell pre-clean, LED component cleaning, and general electronics degreasing. Meets entry-level electronic purity requirements with total metals ≤50 ppb and particles ≤500 ct/mL. The most cost-effective option where G2–G5 specifications are not required.
