Description

Actarit-D4 is a deuterated analog of Actarit, a compound of significant interest in pharmaceutical research and development. This stable isotope-labeled standard is essential for ensuring the accuracy and reliability of quantitative analytical methods, particularly in pharmacokinetic and metabolic studies. It is a critical tool for researchers and quality control laboratories in the pharmaceutical industry who require precise internal standards for mass spectrometry (LC-MS/MS, GC-MS).

Application

• Used as an internal standard in quantitative bioanalysis (LC-MS/MS, GC-MS) for accurate measurement of Actarit in biological matrices.
• Critical for conducting pharmacokinetic (PK) and drug metabolism studies to understand the absorption, distribution, metabolism, and excretion of Actarit.
• Facilitates method development and validation in analytical laboratories to meet regulatory requirements for drug testing.
• Supports impurity profiling and stability studies of pharmaceutical formulations containing Actarit.
• Enables isotope dilution mass spectrometry techniques, which are the gold standard for achieving high analytical precision.
• Employed in clinical research for monitoring drug levels in patient samples during trials.
