Yes, it does not exist in nature as a pure substance.
Which element does not exist in its pure form but must be derived from compounds?
There are many elements that do not exist in nature in pure form, especially the highly reactive ones toward either end of the periodic table, such as sodium and chlorine. These are always derived from compounds. Also the only metal that is found in its pure form in nature is gold due to its extreme unreactivity. Your question hints at something but is incomplete.
