Molecular interaction studies on pharmaceutical drug of 2-[1-(aminomethyl) cyclohexyl] acetic acid in water of various concentrations at 303K


The measurement of ultrasonic velocity in pure liquids and mixtures is an important tool to study the physico- chemical properties and also explains the nature of molecular interactions. The study of thermodynamic parameters to explain molecular interaction of drugs in aqueous or non- aqueous medium provides useful information in medicinal and pharmaceutical chemistry. In present work molecular interaction of aqueous solution of 2-[1-(aminomethyl) cyclohexyl] acetic acid at different concentrations at 303K was studied by measuring ultrasonic velocity, density and viscosity of the solution. The ultrasonic parameters such as adiabatic compressibility, free volume, free length, acoustic impedance, absorption coefficient, viscous relaxation time, available volume and Lenard Jones Potential were calculated. These parameters explained formation of hydrogen bond and molecular interaction existing in the solution
