Dimethyl sulfate yog cov tshuaj sib xyaw nrog cov mis (CH₃O)₂SO₂. Raws li lub diester ntawm methanol thiab sulfuric acid, nws cov mis yog feem ntau sau raws li (CH₃)₂SO₄ los yog Me₂SO₄, qhov twg CH₃ los yog kuv yog methyl. Me₂SO₄ feem ntau yog siv los ua cov tshuaj methylating hauv cov organic synthesis.
