CAS 4378-06-7: Butanoic acid, anhydride with phosphoric acid (1:1)

Description: Butanoic acid anhydride with phosphoric acid (1:1), identified by CAS number 4378-06-7, is a chemical compound that combines the properties of butanoic acid and phosphoric acid. This substance typically appears as a colorless to pale yellow liquid and is characterized by its strong odor reminiscent of rancid butter, which is indicative of the butanoic acid component. It is known for its reactivity, particularly in esterification and acylation reactions, making it useful in organic synthesis and chemical manufacturing. The presence of phosphoric acid enhances its role as a dehydrating agent, facilitating the removal of water in various chemical processes. This compound is soluble in organic solvents but may exhibit limited solubility in water due to its hydrophobic butanoic acid moiety. Safety precautions are essential when handling this substance, as it can be corrosive and may cause irritation to skin and mucous membranes. Proper storage and handling protocols should be followed to mitigate any potential hazards associated with its use.
