Application

Phthalic acid mono-2-ethylhexyl ester can be used as a precursor:
  • To synthesize dioctyl phthalate, a widely used plasticizer, via esterification reaction with 2-ethylhexanol.
  • To prepare a fluorescent probe, 2-[[(3′,6′-dihydroxy-3-oxospiro[isobenzofuran-1(3H),9′-[9H]xanthen]-5-yl)amino]carbonyl] 2-ethylhexyl benzoic acid ester, to detect toxic metabolite mono-2-ethylhexyl phthalate (MEHP).

Endocrine active compounds with structural similarities to natural hormones such as 17β-estradiol (E2) and androgen are suspected to affect the human endocrine system by inducing hormone-dependent effects. This study aimed to detect the (anti-)estrogenic and (anti-)androgenic activities of mono-(2-ethylhexyl) phthalate
