Avobenzone Specification

Avobenzone (CAS NO.70356-09-1) is also named as 1,3-Propanedione, 1-(4-(1,1-dimethylethyl)phenyl)-3-(4-
methoxyphenyl)- ; 1-(4-(1,1-Dimethylethyl)phenyl)-3-(4-methoxyphenyl)-1,3-propanedione ; 1-(p-tert-Butylphenyl)-3-(p-methoxyphenyl)-1,3-propanedione ; Avobenzona ; Avobenzona [INN-Spanish] ; Avobenzonum ; Avobenzonum [INN-Latin] ; HSDB 7423 ; Parsol 1789 ; UNII-G63QQF2NOX . It is a dibenzoylmethane derivative. Avobenzone is sensitive to the properties of the solvent, being relatively stable in polar protic solvents and unstable in nonpolar environments. Avobenzone reacts with minerals to form colored complexes. It also reacts with boron trifluoride to form a stable crystalline complex that is highly fluorescent under UV irradiation.
