Pharmaceutical drugs development brings together chemistry disciplines for designing and controlling their quality. Combined fields as Raman spectroscopies, organic and analytical chemistry are between those disciplines .
First, we will reveal how one single test by Raman spectroscopy ensures the performance and quality control of nasal sprays.
Second, we will discuss how the Organic chemistry based prediction of genotoxic impurities formation and Analytical chemistry "fit to purpose" methods make possible the routine measurement of down to one ppm level of these impurities .
