This title includes a number of Open Access chapters.The science of chemistry is so broad that it is normally broken into fields or branches of specialization. The manufacture of drugs and dyes is one of the most practical industrial applications of chemistry. This collection presents the reader with a broad spectrum of chapters on drugs and dyes,
