Monobutyl Phthalate-d4 is a deuterium-labeled version of Monobutyl Phthalate. The incorporation of deuterium atoms makes Monobutyl Phthalate-d4 an ideal internal standard for quantitative analysis, enabling precise measurement of Monobutyl Phthalate in complex matrices such as environmental samples, biological tissues, and fluids. Monobutyl Phthalate is believed to act as a proton donor, donating protons to other molecules in the vicinity and thus affecting the pH of the local environment. Additionally, it has been suggested that Monobutyl Phthalate may act as a ligand, binding to certain molecules and affecting their activity.
