Description

Marbofloxacin-D8 is a deuterium-labeled internal standard of the veterinary fluoroquinolone antibiotic, Marbofloxacin, specifically designed for analytical applications. This stable isotope-labeled compound is essential for ensuring the accuracy and reliability of quantitative mass spectrometry analyses. It is a critical tool for researchers and quality control laboratories in the pharmaceutical and veterinary sectors who require precise measurement of Marbofloxacin in complex matrices such as biological fluids, tissues, and environmental samples.

Application

• Primary use as an Internal Standard for the quantitative analysis of Marbofloxacin via LC-MS/MS (Liquid Chromatography-Tandem Mass Spectrometry).
• Method development and validation for pharmacokinetic and bioequivalence studies in veterinary medicine.
• High-precision residue testing in food safety programs to monitor Marbofloxacin levels in animal-derived products (meat, milk, eggs).
• Environmental monitoring and analysis of veterinary pharmaceutical runoff.
• Supporting research in veterinary drug metabolism and disposition.
• Quality control and assurance in the manufacturing of Marbofloxacin active pharmaceutical ingredients (APIs) and finished dosage forms.
