Usage:

It is used to synthesize various carbamate pesticides, such as carbapenem, and can also be used as an intermediate for the herbicide sulfamethoxazole.

Used for the synthesis of pharmaceutical intermediates, such as ciprofloxacin, norfloxacin (norfloxacin), ciprofloxacin lactate, and other active pharmaceutical ingredients, mainly used as a methylation agent.

As a solvent for solvent based adhesives, especially polyurethane adhesives, it can also be used in industries such as coatings and inks to replace some toxic solvents and produce environmentally friendly products.

Used for the production of methyl isocyanates, and subsequently for the production of certain carbamate pesticides such as insecticides, fungicides, herbicides, etc.

It can be used as a methylation and carbonylation agent in chemical synthesis, and can also be used to prepare pesticides and herbicides.

It can be used to synthesize polymer materials such as polycarbonate, diphenyl carbonate, isocyanate, and allyl diethylene glycol carbonate.

It can be used as a plasticizer and diluent in adhesives, and can also improve the viscosity and adhesion of the adhesive.
