Basic Information and Parameters

Dimethyl sulfate, with the CAS number 77 - 78 - 1, is a colorless to light yellow, oily liquid. It has a molecular formula of C₂H₆O₄S and a molecular weight of approximately 126.13 g/mol. This product features high - quality and a low price, making it an attractive option for various industries.

It has a density of about 1.332 g/cm³ at 20°C, a melting point of - 31.8°C, and a boiling point of 188.5°C. Dimethyl sulfate is slightly soluble in water and decomposes slowly in it, while it is miscible with organic solvents such as ethanol and ether.

Uses of the Product

Dimethyl sulfate is a widely used methylating agent in the chemical industry. It is used in the synthesis of various organic compounds, such as pharmaceuticals, pesticides, dyes, and perfumes. In the pharmaceutical industry, it is employed in the synthesis of some important drugs. For example, it can be used to introduce methyl groups into the molecular structure of certain drug candidates, which may improve their pharmacological properties.

In the field of pesticides, dimethyl sulfate is used in the production of some high - efficiency pesticides. It can help in the modification of the chemical structure of pesticides, enhancing their insecticidal or herbicidal activities. Additionally, it is used in the dye industry to synthesize some special dyes with unique color - yielding properties.

How to Use the Product

When using dimethyl sulfate, strict safety precautions should be taken. It is a highly toxic and corrosive substance. First, proper personal protective equipment, including chemical - resistant gloves, goggles, and a respirator, should be worn. The operation should be carried out in a well - ventilated fume hood to prevent the inhalation of its vapors.

For laboratory - scale use, measure the appropriate amount of dimethyl sulfate using a pipette or a burette under a fume hood. When adding it to a reaction system, add it slowly while stirring to ensure uniform mixing. In industrial - scale applications, use specialized dosing equipment to ensure accurate and safe addition.

After use, all equipment in contact with dimethyl sulfate should be thoroughly cleaned. Any spills should be immediately cleaned up using appropriate absorbents, and the waste should be disposed of in accordance with relevant environmental protection regulations.

Usage Case Studies

Case 1: Pharmaceutical Synthesis
A pharmaceutical company was synthesizing a new anti - cancer drug. They used dimethyl sulfate as a methylating agent in one of the key reaction steps. By carefully controlling the reaction conditions, including temperature, reaction time, and the amount of dimethyl sulfate added, they successfully introduced the methyl group into the target molecule. The yield of the intermediate product reached 80%, which was a significant improvement compared to previous synthetic methods without using dimethyl sulfate. After further purification and subsequent reaction steps, the final anti - cancer drug showed excellent in - vitro and in - vivo anti - tumor activities.

Case 2: Pesticide Production
A pesticide manufacturer was developing a new type of herbicide. Dimethyl sulfate was used to modify the chemical structure of the lead compound. Through a series of reaction optimization experiments, they found that the use of dimethyl sulfate could significantly enhance the herbicidal activity of the final product. In field trials, the new herbicide showed a 90% control rate against common weeds, which was much higher than the previous generation of herbicides.
