Description

Fingolimod-D4 CAS NO 1346747-38-3 is a deuterated analog of the active pharmaceutical ingredient Fingolimod, a sphingosine 1-phosphate receptor modulator. This stable isotope-labeled compound is essential for quantitative bioanalytical studies, providing an internal standard for precise and accurate mass spectrometry analysis. It is primarily required by pharmaceutical R&D laboratories, contract research organizations (CROs), and academic institutions engaged in pharmacokinetic, metabolism, and clinical studies of Fingolimod.

Application

• Internal standard for the quantitative LC-MS/MS analysis of Fingolimod and its metabolites in biological matrices (plasma, serum, tissue).
• Use in drug metabolism and pharmacokinetics (DMPK) studies to ensure data accuracy and regulatory compliance.
• Critical component in bioanalytical method development and validation for clinical trial sample analysis.
• Supporting research into the mechanism of action and metabolic pathways of sphingosine 1-phosphate receptor modulators.
• Application in forensic and anti-doping analysis where precise quantification of Fingolimod is required.
