IR spectra of paracetamol and phenacetin in the range 2000 cm-1400 cm-1 : 1) CDCl 3 solution of paracetamol; 2) CDCl 3 solution of phenacetin; 3) monoclinic
Introduction
A transmission FTIR spectroscopic method was developed for direct, inexpensive and fast quantification of paracetamol content in solid pharmaceutical formulations
