Butanedioic acid, dimethyl ester, also called dimethyl glutarate or glutaric acid dimethyl ester (CAS No. 616-38-6), is an organobutanedioic acid ester with an aldehyde group. It is a liquid at room temperature and has a faint unpleasant odor.


It is used as a reagent in the synthesis of organic and inorganic compounds, as well as a starting material for the preparation of other materials. It is also used as a corrosion inhibitor in metal finishing. It is used to produce various aromatic esters, including diethyl glutarate, which is used as a plasticizer in many applications.


The aldehyde group in dimethyl glutarate provides a convenient starting material for the synthesis of various carbon-containing compounds, such as dyes, pigments, pharmaceuticals, and fragrances. Other applications include the use of dimethyl glutarate in the manufacturing of polymers and in the production of adhesives, sealants, and coatings.


Dimethyl glutarate is also commonly used as an antifoaming agent in the production of polymers, fibers, and coatings. It is an effective anti-foaming agent and can reduce the surface tension of liquids, enabling the formation of a fine foam. Its high boiling point makes it an ideal anti-static agent for volatile liquids.


Dimethyl glutarate is an important intermediate in the synthesis of polyamides. It is used in the production of nylon, polyurethanes, polyesters, and polystyrene. It is also used in the production of polycarbonates, polyvinyl chloride and polyethylene oxide.


It can be used in the manufacture of polymeric materials, such as paints and coatings. Its use as a corrosion inhibitor makes it an important component in the protection of metals from corrosion. It is also commonly used in cleaning agents, adhesives, and lubricants. Its corrosion-inhibiting action makes it an important component in the manufacture of gear oil, fuel additives, and automotive oil.
