1,2,4-Butanetricarboxylic acid(CAS: 923-42-2)

1,2,4-Butanetricarboxylic acid is a crystalline solid with a molecular weight of approximately 154.08 g/mol. It is slightly soluble in water but highly soluble in organic solvents like ethanol. Chemically, it is a tricarboxylic acid and exhibits moderate reactivity, particularly in esterification and amide formation reactions.

1,2,4-Butanetricarboxylic acid is typically synthesized through the hydration of 1,2,4-butatriene followed by oxidation. The process often uses chromium(VI) salts as catalysts to ensure high selectivity and yield. The reaction is carried out under controlled conditions to optimize product purity and yield.

1,2,4-Butanetricarboxylic acid is used in various industries, including pharmaceuticals for the synthesis of certain drugs, polymers for plastic production, and in the development of sensors and semiconductors due to its carboxylic acid functionality that is useful in various chemical modifications and reactions.

When handling 1,2,4-Butanetricarboxylic acid, protective equipment such as gloves, goggles, and lab coats should be worn to protect against skin and eye irritation. It should be stored in a dry, well-ventilated area, away from heat and sources of ignition. In case of spill, it should be cleaned up carefully according to the Material Safety Data Sheet (MSDS/SDS) guidelines to prevent environmental contamination and exposure risks.
