Description

Monoethyl Phthalate-D4 is a stable isotope-labeled analog of monoethyl phthalate, where four hydrogen atoms are replaced by deuterium. This compound serves as a critical internal standard for the accurate quantification and metabolic tracing of phthalate esters in complex matrices. It is essential for researchers and quality control laboratories in the environmental monitoring, toxicology, and pharmaceutical sectors who require high-precision analytical results.

Application

• Internal Standard for GC-MS and LC-MS/MS analysis of phthalate metabolites.
• Tracer compound in pharmacokinetic and metabolic pathway studies.
• Reference material for method development and validation in environmental testing labs.
• Calibration standard for ensuring accuracy in human biomonitoring programs.
• Quality control reagent in the production of deuterated chemical standards.
• Research tool in studying the environmental fate and biodegradation of phthalates.
