Monobutyl phthalate

Description:
Monobutyl phthalate (MBP), with the CAS number 131-70-4, is an organic compound belonging to the phthalate family, which are esters of phthalic acid. It is characterized by its clear, colorless liquid form and has a slightly sweet odor. MBP is primarily used as a plasticizer, enhancing the flexibility and durability of various polymers, particularly polyvinyl chloride (PVC). Its chemical structure consists of a butyl group attached to one of the carboxyl groups of phthalic acid, which influences its physical and chemical properties. MBP is soluble in organic solvents but has limited solubility in water. It is known to exhibit low volatility and moderate toxicity, raising concerns regarding its potential environmental and health impacts. As a result, its use is regulated in many regions, particularly in products intended for children. Overall, MBP plays a significant role in industrial applications, but its safety profile necessitates careful handling and consideration of alternatives in certain contexts.
