The thermodynamic relationship between FI and FII of ethyl 4-aminobenzoate (benzocaine) has been investigated. Slurry conversion experiments show that the transition temperature below which FI is stable is located between 302 K-303 K (29 °C-30 °C). The polymorphs FI and FII have been characterised by infrared spectroscopy (IR), Raman spectroscopy, transmission powder X-ray diffraction (XRPD) and differential scanning calorimetry (DSC).

- The study investigates how fenoxycarb molecules interact and aggregate in isopropanol solutions using several analytical techniques like dynamic light scattering and infrared spectroscopy.
- Clusters of molecules can grow up to almost one micrometre in size and tend to increase in size with higher solute concentrations and longer time periods under stagnant conditions.
- The research also notes that factors like temperature, filtration, and concentration levels significantly affect cluster sizes and their behavior, pointing to complex dynamics in solution that influence molecular interactions.
