Description

Diisononyl Phthalate-D4 is a deuterated analog of diisononyl phthalate (DINP), a high-molecular-weight phthalate plasticizer. This compound is specifically designed for use as an internal standard in analytical chemistry, enabling precise quantification and method development via mass spectrometry. It is essential for researchers and quality control laboratories requiring high accuracy in trace analysis of phthalates. The product is primarily used in environmental testing, polymer analysis, and regulatory compliance monitoring within the plastics and consumer goods industries.

Application

• Internal Standard for Mass Spectrometry (MS): Used as a deuterated internal standard for the accurate quantification of DINP and related phthalates in GC-MS and LC-MS methods.
• Polymer and Plasticizer Analysis: Critical for determining phthalate migration and content in PVC products, toys, food packaging, and medical devices.
• Environmental Monitoring: Employed in the analysis of water, soil, and dust samples for phthalate contamination studies.
• Method Development and Validation: Serves as a key reference material for developing and validating robust analytical protocols in compliance with ISO, EPA, and other international standards.
• Quality Control & Assurance: Used in industrial QC labs to ensure the purity and consistency of phthalate-based plasticizers and final products.
• Toxicological and Biomonitoring Studies: Facilitates precise measurement of phthalate metabolites or parent compounds in biological matrices for health and safety research.
