1,2-Dimethoxybenzene (Veratrole) (CAS: 91-16-7), a dimethoxybenzene with the methoxy groups at ortho-positions. Veratrole is relatively electron-rich and thus readily undergoes electrophilic substitution. Preparation Prepared by methylation of pyrocatechol. Veratrole is used as a starting raw material to pharmaceutical and agrochemical industries.
Veratrole is the fungicide dimethomorph, intermediates of flumorph. Veratrole is used as an intermediate in organic synthesis, in the pharmaceutical industry, for the synthesis of tetrahydropalmatine, verapamil and so on.
Veratrole is the raw material of Veratraldehyde (CAS: 120-14-9), Veratric Acid (CAS: 93-07-2), Veratone (CAS: 776-99-8).
