Description

Oxybutynin D11 Hydrochloride is a deuterium-labeled internal standard of the anticholinergic agent oxybutynin, specifically designed for high-precision analytical applications. This compound is essential for ensuring accurate quantification and method validation in pharmacokinetic and bioanalytical studies. It is primarily utilized by pharmaceutical R&D laboratories, contract research organizations (CROs), and analytical service providers engaged in drug metabolism and mass spectrometry-based assays.

Application

• Primary use as an internal standard for the quantification of oxybutynin and its metabolites in biological matrices via LC-MS/MS and GC-MS.
• Critical component in bioanalytical method development and validation for clinical and preclinical studies.
• Supporting pharmacokinetic (PK) and pharmacodynamic (PD) research to understand drug absorption, distribution, metabolism, and excretion.
• Ensuring data integrity and regulatory compliance in Good Laboratory Practice (GLP) and Good Clinical Practice (GCP) environments.
• Application in doping control and forensic analysis for the detection of anticholinergic substances.
• Use in stable isotope dilution analysis to achieve superior accuracy and precision over conventional analytical techniques.
