Dicarboxylic acids are organic compounds that contain two functional carboxylic acid (–COOH) groups. Industrially, they are important in producing polyester, polyols, polyamides, and nylon and as a precursor to active pharmaceutical ingredients and additives. Dicarboxylic acids are important water-soluble...
Dicarboxylic acids(DCAs) (e.g. adipic, suberic, sebacic acids) are found in all identified intramitochondrial β-oxidation defects.185Hale and Bennett39point out several limitations to the value of these compounds in the recognition of FAO defects. (i) These DCAs may be seen in children rec...

The readily available cis/trans mixture of 1,2-cyclobutanedicarboxylic acid undergoes a quantitative isomerization in 12N HCl to the trans-diacid (as monitored by NMR spectroscopy). The latter is resolved to the (+)- and (-)-trans-diacids by modified literature and patented methods. The ...
