2-Ethylhexyl 4-(dimethylamino)benzoate (commonly called octyl dimethyl PABA) is a UV-absorbing chemical widely used in pharmaceuticals and cosmetics as a UVB filter in sunscreens. It is a UVB-only filter, absorbing UV radiation between 280–315 nm with peak absorption around 311 nm, and does not provide broad-spectrum (UVA plus UVB) protection. This pharma-grade compound has a CAS number of 21245-02-3, molecular formula (CH₃)₂NC₆H₄CO₂CH₂CH(C₂H₅)(C₄H₉), and a molecular weight of 277.40 g/mol. It is stable at ambient storage conditions but requires careful handling due to its Danger signal word classification. Molekula supplies 2-Ethylhexyl 4-(dimethylamino)benzoate pharma grade from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
