Product Introduction
Introductions
Difluoroacetic acid is mainly used as a pharmaceutical and pesticide intermediate. It can also be used as a new reagent for the C-H difluoromethylation of heteroaromatic compounds. It can also be used in dry etching. And polysilicon has a high selectivity ratio, which can inhibit the damage to silicon oxide.
