Used primarily as a metabolite and intermediate in the breakdown of nitroglycerin in the body, 2-mononitroglycerin contributes to the vasodilatory effects associated with nitroglycerin therapy. It plays a role in the treatment of cardiovascular conditions such as angina pectoris by helping relax blood vessels and improving blood flow. Though less potent than nitroglycerin, its presence prolongs the overall therapeutic effect. It is also studied in pharmacokinetic research to understand the metabolism and efficacy of organic nitrates in medical treatments.
