Lisinopril-d₅（Cat No.:R044922）is a deuterated form of lisinopril, an angiotensin-converting enzyme (ACE) inhibitor widely used to manage hypertension, heart failure, and related cardiovascular conditions. In Lisinopril-d₅, five hydrogen atoms are replaced with deuterium, making it ideal as an internal standard in LC-MS/MS analysis for accurate quantification of lisinopril in biological samples. It retains the pharmacological properties of the non-labeled compound while providing enhanced analytical performance. Lisinopril-d₅ is valuable in pharmacokinetic, bioequivalence, and metabolic studies.
