Used in ophthalmology, particularly in the development of treatments for glaucoma and ocular hypertension. It functions as an intermediate or metabolite in the metabolic pathway of bimatoprost, a prostaglandin analog that enhances aqueous humor outflow from the eye, thereby reducing intraocular pressure. Due to its structural similarity to active prostaglandins, it may retain some biological activity, though typically less potent than the parent compound. Its presence or use in formulations can influence the duration and effectiveness of intraocular pressure reduction. Also studied in research settings to understand metabolic stability and structure-activity relationships of prostaglandin analogs used in eye care.
