| Description | (2-Hydroxyethoxy)acetic acid (β-hydroxyethoxyacetic acid) is the primary urinary metabolite of 1,4-dioxane, serving as a reliable and sensitive short-term biomarker in urine. |
| In vitro | (2-Hydroxyethoxy)acetic acid (HEAA) exhibits a pH-dependent equilibrium with its cyclic lactone form, dioxan-2-one, maintaining a stable open-chain structure in acidic conditions[1]. |
| In vivo | The primary metabolic route for 1,4-Dioxane involves its oxidation by cytochrome P450 monooxygenase into (2-Hydroxyethoxy)acetic acid (β-hydroxyethoxyacetic acid; HEAA), which is subsequently rapidly eliminated through urinary excretion[1]. |
| Synonyms | β-hydroxyethoxyacetic acid, HEAA |
