Description

Di-n-Pentyl Phthalate-D4 is a deuterated analog of di-n-pentyl phthalate, where four hydrogen atoms are replaced by deuterium, making it a valuable stable isotopically labeled compound. This labeling is critical for applications requiring precise internal standards in analytical chemistry, eliminating interference and enabling accurate quantification. It is primarily needed by analytical laboratories, environmental testing facilities, and research institutions conducting advanced mass spectrometry (MS) and nuclear magnetic resonance (NMR) studies.

Application

• Internal Standard for GC/MS and LC/MS analysis of phthalate esters and plasticizers.
• Quantitative reference material in environmental monitoring for phthalate contamination.
• Tracer compound in metabolic and pharmacokinetic research studies.
• Deuterated standard for NMR spectroscopy to aid in structural elucidation.
• Calibration standard in analytical method development and validation.
• Component in the synthesis of labeled polymers for degradation studies.
