CATO's Azithromycin-D5: Powering Precision Analytics

Azithromycin-D5 is synthesized by selectively replacing five specific hydrogen atoms in the azithromycin molecular structure with deuterium. It retains identical chemical properties while exhibiting distinct mass spectrometric characteristics.

Product Code: CCAD301941 

Molecular Formula: C38H67D5N2O12 

Molecular Weight: 754.02 

Purity: 99.5%

Applications

LC-MS/MS Analysis: Enables precise quantitative determination of azithromycin concentrations in biological samples.

Bioequivalence Studies: Supports evaluation of the in vivo absorption and metabolic profiles of new formulations during drug development.

Pharmacokinetic Studies: Tracks drug distribution, metabolism, and excretion within biological systems.

Stability Testing: Confirms robustness and reproducibility of analytical methods.

Recent studies have demonstrated that deuterium labeling significantly enhances the accuracy of mass spectrometry analysis, particularly in the context of complex biological samples. Because deuterated and non-deuterated molecules exhibit virtually identical chromatographic behaviors yet are clearly distinguishable by mass spectrometry, the quantitative analysis results are more precise and reliable, effectively mitigating interference from matrix effects.

With the continuous advancement in analytical technology, the demand for high-purity isotope-labeled compounds continues to rise, offering increasingly reliable quantitative tools for pharmaceutical analysis and clinical diagnostics. The high-purity Azithromycin-D5 standard provided by CATO offers a precise and stable analytical approach, facilitating more reliable experimental data acquisition in drug development and quality control.
