This compound is suberic acid (an eight-carbon dicarboxylic acid) with one of its two carboxylic acids converted to a methyl ester, leaving the other free. That asymmetry — one reactive free acid, one “capped” ester — makes it a useful building block for selectively functionalizing just one end of the eight-carbon chain.
This compound is used as a building block in polymer manufacturing (asymmetric monomer chemistry) and in pharmaceutical intermediate manufacturing, where the free carboxylic acid end can be selectively coupled (e.g., to a hydroxamic acid or amide) while the methyl ester end remains protected for later use.
