What is Malonic acid CAS 141-82-2?
Malonic acid (CAS 141-82-2), as a highly active dibasic acid, its core value lies in the activated methylene group in its molecule and its easy decarboxylation property, which supports key fields such as medicine (over 60% of its applications), industry (surface treatment/electroplating), and agricultural chemistry.
Environmental advantages: When used as an aluminum treatment agent, it decomposes without causing pollution, which is in line with the trend of green production.
The key to synthesis: In industry, the hydrolysis of cyanoacetic acid is the main method, and the risk of cyanide must be strictly controlled.
Safety reminder: Although it is of low toxicity, standardized operation is still necessary to avoid irritation and pay attention to the impact of environmental emissions.

Malonic acid CAS 141-82-2 safety
Toxicity data:
Low toxicity: Oral LD₅₀ in mice is 1.54 g/kg, which is irritating to the skin and mucous membranes (weaker than oxalic acid).
Risk identification: Xn (Harmful), Xi (Irritating), Risk code R22 (Harmful if swallowed), R36/37/38 (Irritating to eyes/respiratory tract/skin).
Protection and storage
When operating, protective clothing and gas masks should be worn to avoid contact with skin and eyes.
Store in a sealed container in a cool and dry place, away from oxidants (which are prone to reactions).
Environmental risk:
The water body may have an acidified environment that affects aquatic organisms, and waste must be disposed of in compliance with regulations.
