Sensitization risk High

N-ETHYL-3-NITRO PABA is classified with GHS hazard statements, including Harmful if swallowed (H302), May cause an allergic skin reaction (H317), and Harmful to aquatic life with long-lasting effects (H412). It is further designated as a Skin Sensitizer Category 1. The parent compound, PABA, is prohibited in Europe due to documented concerns about skin irritancy, allergenicity, and its status as a suspected carcinogen. Another PABA derivative, Ethylhexyl dimethyl PABA, has demonstrated increased mutagenicity following sun exposure, raising concerns about its potential to contribute to sun-induced cellular damage.
