Use
1. It is mainly used in the synthesis of pesticides, medicines and organic chemical raw materials. It is currently the main raw material for the production of herbicide rice and grass.
2. o-Methylbenzoic acid is an intermediate of fungicides such as rust-killing amine, phenoxystrobin, trifloxystrobin and herbicide bensulfuron-methyl.
3. It is used as an organic synthesis intermediate for pesticides and fungicides such as phosphoramide, perfume, vinyl chloride polymerization initiator MBPO, m-cresol, color film developer.
4. Used in organic synthesis intermediates, pesticide industry to prepare fungicide phosphoramide, can also be used in perfumery and film.
5. o-Methylbenzoic acid is an important intermediate for the synthesis of many fine chemicals, used in the preparation of initiator MBPO, fungicide phosphoramide, perfume, film and so on.
