Description

3alpha-Hydroxy Pravastatin Lactone-D3 (CAS 1329809-35-9) is a deuterium-labeled impurity corresponding to the 3alpha-hydroxy lactone form of pravastatin. The tri-deuterated species provides a +3 mass shift relative to the protiated impurity, facilitating unambiguous identification and quantification by LC-MS and high resolution mass spectrometry. Chemically characterized by lactone ring closure and a secondary hydroxyl at C-3 alpha, this impurity can arise during acid-catalyzed cyclization or oxidation steps in synthesis. It is supplied as a characterized reference material with chromatographic retention properties and stability data to support impurity profiling, method development, and regulatory-compliant impurity control.
