CAS 77-78-1

Dimethyl sulfate

Description:

Dimethyl sulfate (CAS 77-78-1) is a colorless, oily liquid with a sweet, pungent odor. It is an organosulfur compound and is classified as a highly toxic alkylating agent. Dimethyl sulfate is known for its ability to methylate nucleophiles, making it a useful reagent in organic synthesis, particularly in the production of methylated compounds. However, its toxicity poses significant health risks, as it can cause severe burns upon contact with skin and is a potent carcinogen. It is also harmful if inhaled or ingested, leading to respiratory distress and other serious health effects. Dimethyl sulfate is soluble in water and organic solvents, which enhances its reactivity. Due to its hazardous nature, it is subject to strict regulations regarding its handling and disposal. Safety precautions, including the use of personal protective equipment and proper ventilation, are essential when working with this compound in laboratory or industrial settings.

Controlled Product

CAS: 77-78-1

Dimethyl sulfate is the organic compound with the formula CH3OSO2. It is a colorless liquid that can be obtained by reacting methyl alcohol with sulfur trioxide. Dimethyl sulfate has been used in analytical chemistry as an extractant for basic proteins and picolinic acid. Dimethyl sulfate is also found in nutrient solutions, where it serves as a source of sulfate for plants. The dimethyl sulfate molecule contains two methyl groups that are attached to the sulfur atom, which results in a molecule with two intramolecular hydrogen bonds. This feature gives dimethyl sulfate a high boiling point relative to its molecular mass of 114 g/mol and allows it to be crystallized from solution at room temperature. Dimethyl sulfate is also used as an intermediate in the production of polymerase chain reaction (PCR) reagents, such as primers and nucleotides.
