Description

Bis(4-Methyl-2-Pentyl) Phthalate-D4 is a deuterated isotopologue of a high-molecular-weight phthalate ester, specifically designed for use as an internal standard in analytical chemistry. This compound is essential for ensuring the accuracy and reliability of quantitative analyses, particularly in mass spectrometry, by correcting for variations in sample preparation and instrument response. It is a critical tool for researchers and quality control laboratories in the environmental monitoring, polymer science, and regulatory compliance sectors who require precise measurement of phthalate compounds.

Application

• Internal Standard for GC-MS and LC-MS analysis of phthalate esters and plasticizers.
• Quantitative reference material in environmental testing for phthalate contamination in water, soil, and air samples.
• Method development and validation in analytical laboratories for polymer and material science.
• Quality control and assurance in the production of plastics, coatings, and adhesives.
• Tracer studies in metabolic and pharmacokinetic research utilizing deuterated analogs.
• Calibration standard for regulatory compliance testing (e.g., REACH, FDA, EPA methods).
