Isobutyl isobutyrate, United States Pharmacopeia (USP) Reference Standard

Based upon a water solubility of 1000 mg/L(1) and a vapor pressure of 4.33 mm Hg at 25 deg C(2), the Henry's Law constant for 2-methylpropyl isobutyrate can be estimated to be 8.22X10-4 atm cu m/mole; a Henry's Law constant of this magnitude indicates that volatilization from environmental waters is important, but may not be rapid(3). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep flowing 1 m/sec with a wind velocity of 3 m/sec) can be estimated to be about 4.8 hours(3,SRC). The volatilization half-life from a model environmental pond (2 meters deep) can be estimated to be about 3 days(4,SRC). 2-Methylpropyl isobutyrate has a relatively high vapor pressure(2) which suggests that evaporation from dry surfaces will occur(SRC).

Based upon a water solubility of 1000 mg/L at 20 deg C(1), the Koc for 2-methylpropyl isobutyrate can be estimated to be 98 from a linear regression-derived equation(2,SRC). This Koc estimation indicates high soil mobility(3).
