• 使用

  1,2-Dimethoxybenzene was used to investigate the electroantennogram response of vine weevil, Otiorhynchus sulcatus to plant volatiles.

• 定義

  ChEBI: A dimethoxybenzene with the methoxy groups at ortho-positions.

• 製造方法

  Prepared by methylation of pyrocatechol.

• 一般的な説明

  1,2-Dimethoxybenzene reacts with Li{N(SO₂CF₃)₂} to yield molecular crystal [Li{N(SO₂CF₃)₂}{C₆H₄(OCH₃)₂}₂] having solid-state lithium ion conductivity. It is a potential pollinator attractant of the nocturnal moth Hadena bicruris.

• 毒性学

  Data from 1,2-dimethoxybenzene and read-across analog 1,4-dimethoxybenzene (CAS # 150-78-7) show that 1,2-dimethoxybenzene is not expected to be genotoxic. Data show that there are no safety concerns for 1,2-dimethoxybenzene for skin sensitization under the current declared levels of use. The repeated dose, reproductive, and local respiratory toxicity endpoints were evaluated using the TTC for a Cramer Class I material, and the exposure to 1,2-dimethoxybenzene is below the TTC (0.03 mg/kg/day, 0.03 mg/kg/day, and 1.4 mg/day, respectively). The phototoxicity/photoallergenicity endpoints were evaluated based on UV spectra; 1,2-dimethoxybenzene is not expected to be phototoxic/photoallergenic. For the environmental endpoints, 1,2-dimethoxybenzene is not a PBT as per the IFRA Environmental Standards, and its risk quotients (i.e., PEC/PNEC) for the aquatic environment, based on its current volume of use in Europe and North America, are < 1

• 純化方法

  Steam distil veratrole, then fractionally distil it from BaO, CaH2 or Na. Crystallise it from *benzene or low-boiling pet ether at 0o. Fractionally crystallise it from its melt. Store it over anhydrous Na2SO4. [Beilstein 6 IV 5564.]
