Description

Di-iso-Butyl Phthalate-3,4,5,6-D4 is a deuterium-labeled isotopologue of diisobutyl phthalate (DIBP), a high-purity analytical standard essential for modern research and quality control. This compound matters because it serves as a critical internal standard for the precise quantification of phthalate plasticizers using advanced techniques like gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-tandem mass spectrometry (LC-MS/MS). It is primarily needed by analytical laboratories, environmental testing facilities, and chemical manufacturers engaged in polymer research, regulatory compliance testing, and material safety assessments.

Application

• Internal Standard for Mass Spectrometry: Used as a quantitative reference standard in GC-MS and LC-MS/MS analysis of phthalates in complex matrices.
• Environmental Analysis: Critical for tracing and quantifying DIBP and related phthalate esters in environmental samples like water, soil, and air particulates.
• Polymer & Plasticizer Research: Enables accurate study of plasticizer migration, leaching, and degradation kinetics in PVC and other polymer formulations.
• Regulatory Compliance & Safety Testing: Supports testing for consumer product safety (e.g., toys, food packaging) to meet standards like REACH, CPSC, and FDA guidelines.
• Forensic & Clinical Toxicology: Assists in the detection and measurement of phthalate exposure biomarkers in biological samples.
• Method Development & Validation: Serves as a key reagent for developing and validating robust analytical methods in accredited laboratories.
• Isotope Dilution Analysis: Provides high accuracy and precision in quantification by correcting for analyte loss during sample preparation.
• Pharmaceutical & Biomedical Research: Used in studies investigating the environmental impact and metabolic pathways of phthalate compounds.
