Description

Dimethyl Phthalate (Ring-D4) is a stable isotope-labeled analog of dimethyl phthalate, where four hydrogen atoms on the aromatic ring are replaced by deuterium. This compound is essential as an internal standard for precise quantitative analysis in mass spectrometry, eliminating matrix effects and ensuring accurate measurements. It is primarily required by analytical laboratories, pharmaceutical researchers, and environmental testing facilities engaged in method development and trace-level detection of phthalate compounds.

Application

• Internal Standard for GC-MS and LC-MS analysis of phthalate esters.
• Quantitative reference material in environmental monitoring for phthalate contamination.
• Tracer compound in metabolic and pharmacokinetic studies within pharmaceutical R&D.
• Calibration standard for analytical instrument validation and method accreditation.
• Use in polymer science research to study plasticizer migration and degradation.
• Critical reagent in the development of certified reference materials (CRMs).
