Metabolite Identification
Common NameMono-(2-ethyl-5-hydroxyhexyl) phthalate
DescriptionMono-(2-ethyl-5-hydroxyhexyl) phthalate, also known as 40321-99-1 or phthalic acid mono(2-ethyl-5-hydroxyhexyl) ester, is classified as a member of the benzoic acid esters. Benzoic acid esters are ester derivatives of benzoic acid. 40321-99-1 is considered to be practically insoluble (in water) and acidic. (ChemoSummarizer) Mono-(2-ethyl-5-hydroxyhexyl) phthalate is a metabolite of mono(2-ethylhexyl) phthalate (MEHP) and a secondary metabolite of di(2-ethylhexyl) phthalate (DEHP) [Exposome-Explorer]. Di(2-ethylhexyl) phthalate (DEHP) is added to polyvinyl chloride (PVC) plastics used widely in medical devices and toys to impart flexibility and durability (Pubmed: 16332407).
