As with other scientific subjects, specialization is essential due to the basic complexity of the subject at this level.
At undergraduate level, this will often take the form of elective modules, though specialized courses are also an option. Graduate study will certainly involve specialization.
Many specializations will overlap with other science subjects. Some examples are:
Chemical engineering: like alchemy but less gold-fixated, the purpose of chemical engineering is to convert substances into more useful ones - like medicines – using chemical processes. The focus can be on the actual substance produced or the process of conversation.
Biochemistry: The study of the chemical processes within living organisms, such as those which convert thought into action or make you feel a certain way. This is a massive subject and it is predicted that huge strides will be made in the foreseeable future.
Medicinal chemistry: In a way, this branch of chemistry represents a coming together of the two disciplines above, as it involves synthesizing certain chemicals present in the human body. There will always be a demand for this sort of research, and there’s surely a lot of satisfaction to be had in coming up with life-saving or improving drugs
Astrochemistry: The junction between chemistry and astronomy, the goal of astrochemistry is to discover of what matter in space is composed, and how elements and molecules behave there. You’ll be rooted on earth, so this will involve computational chemistry, spectroscopy (using light to help identify matter), and ingenuity.
Nuclear chemistry: A fairly self explanatory discipline, nuclear chemistry is the study of radioactive elements, how to harness them, and their effects on organisms and matter. It has applications in medicine and energy, and will involve engineering and collaboration with engineers.
