Product Description:
MTHPA is a hydrogenated derivative of phthalic anhydride. Its structure features a partially saturated cyclohexene ring (retaining one double bond) with two anhydride groups (oxygen bridge connecting two carboxylic acid groups) and a methyl (-CH₃) substituent. The hydrogenation reduces aromaticity, enhancing stability and altering reactivity.
