2-Bromo-1,6-dimethyl Ester Hexanedioic Acid is an intermediate in the synthesis of 2-Hydroxyhexanedioic Acid Disodium Salt (H943015). Accumulation and excretion of 2-Hydroxyhexanedioic Acid (with 2-ketoadipic and 2-aminoadipic) in urine can be caused by 2-ketoadipic acidemia, probably without adverse phenotypic effects, due to deficiency of 2-ketoadipic dehydrogenase.
