3β-Ursodeoxycholic Acid is a specialty chemical, specifically a bile acid analog and stereoisomer of ursodeoxycholic acid (UDCA). It is utilized primarily in pharmaceutical research and medicine for liver and gallbladder conditions, helping to dissolve cholesterol gallstones in patients unsuitable for surgery. It manages primary biliary cholangitis by reducing liver enzyme levels and slowing disease progression. It is also applied in certain metabolic disorders to improve bile flow and reduce hepatic toxicity. In dermatology, it is investigated for skin conditions linked to bile acid imbalances. Its anti-inflammatory and cytoprotective properties support diverse therapeutic research applications, often as a pharmaceutical intermediate.
