Description

Miloxacin-D3 is a deuterium-labeled analog of the quinolone antibiotic Miloxacin, specifically designed for use as an internal standard in advanced analytical techniques. This high-purity compound is essential for ensuring the accuracy and reliability of quantitative analyses, particularly in pharmacokinetic and metabolic studies. It is a critical tool for researchers and quality control laboratories in the pharmaceutical, biotechnology, and contract research organization (CRO) sectors who require precise and traceable measurement of the parent compound.

Application

• Internal Standard for LC-MS/MS and GC-MS analysis in bioanalytical method development and validation.
• Quantitative analysis in pharmacokinetic (PK) and pharmacodynamic (PD) studies for drug metabolism and disposition.
• Use in stable isotope dilution assays for the accurate determination of Miloxacin in complex biological matrices (e.g., plasma, serum, tissue).
• Metabolite identification and profiling studies in pharmaceutical research and development.
• Quality control and assurance testing in pharmaceutical manufacturing for batch consistency.
• Environmental fate and residue analysis studies in agrochemical research.
• Forensic analysis for the detection and quantification of quinolone antibiotics.
