Used primarily in the synthesis of pharmaceuticals, particularly as a key intermediate in the production of local anesthetics like procaine and benzocaine. Also serves as a precursor in the manufacture of dyes and UV-absorbing compounds for sunscreens due to its ability to absorb ultraviolet light. In microbiology, it is utilized in culture media formulations to support the growth of certain microorganisms that require it as a growth factor, as it is a precursor to folic acid (vitamin B9). Additionally, it finds use in the development of some hair dyes and cosmetic products for its stabilizing properties.
