[0239] Determination of the purity of compound (bempedoic acid) of formula (V) The level of purity of the purified form of the compound of formula (V) is measured using a high-performance liquid detector equipped with a UV detector. The determination was made using chromatography. Assays for the purified form of the compound of formula (V) are performed at 98-102% (anhydrous solvent-free). It was determined that it falls within the scope of the system.
