Malonic acid with cas registry number of 141-82-2 is is a carboxylic acid, also called for AI3-15375 ; Carboxyacetic acid ; Dicarboxymethane ; Kyselina malonova ; Kyselina malonova [Czech] ; MALONIC ACID ; Methanedicarboxylic acid ; NSC 8124 ; Propanedioic acid ; USAF EK-695 .

It can be prepared in this way: Sodium carbonate generates the sodium salt which is then reacted with sodium cyanide to provide the cyano acetic acid salt via a nucleophilic substitution.

The nitrile group can be hydrolyzed with sodium hydroxide to sodium malonate and acidification affords malonic acid.

Application:

1. It mainly can be used as pharmaceutical intermediates. It also can be used as perfumery, adhesives, resin additives, electroplating polishing agent and so on.

2. It can be used as complexing agent. It also can be used to prepare barbituric salt.

3. Malonic acid is the intermediate of fungicides isoprothiolane. It is also the intermediate of plant growth regulator ethychlozate.

4. Malonic acid and its esters is mainly used as perfumery, adhesives, resin additives, pharmaceutical intermediates, electroplating, polishing agent, explosion control agents, heat welding fluxing additives and the like. In the pharmaceutical industry, it can be used to produce phenobarbital, barbiturates, vitamin B1, vitamin B2, vitamin B6, phenylbutazone, amino acids and so on. Malonic acid can be used as the aluminum surface treatment agent since that malonic acid generates carbon dioxide and water after heated without pollution problems. At this point, it has a great advantage when compared with acidic treating agent like formic acid in the past.

5. It can be used as complexing agent in the determination of beryllium, copper, calibration standard alkaline solution, biochemical studies, organic synthesis, preparing barbiturates, gas chromatography analysis of the standard.
