Chemistry is the study of matter, including its composition and structure, its physical properties, and its reactivity. There are many ways to study chemistry, but, we traditionally divide it into five fields: Organic chemistry, Inorganic chemistry, Biological chemistry, Physical chemistry, and Analysis. Pharmaceutical Analysis is often described as the area of chemistry responsible for characterizing the composition of matter, both qualitatively and quantitatively.In the development of new products which contains mixtures other than the pure material, it is necessary to ascertain composition of mixture which shows the optimum characteristics for which the material has been developed.
