Description

Dimethyl Hexanedioate-D8 is a high-purity, deuterium-labeled derivative of dimethyl adipate, specifically designed for advanced analytical and research applications. This stable isotope-labeled compound is essential for use as an internal standard in mass spectrometry, ensuring precise quantification and reliable data in complex chemical analyses. It is a critical material for researchers and quality control laboratories in the pharmaceutical, environmental testing, and metabolomics sectors, where accurate measurement of adipic acid or its esters is required.

Application

• Internal Standard for Mass Spectrometry (MS): Primary use as a quantitative internal standard in GC-MS and LC-MS analyses for adipic acid, its esters, or related metabolic pathways.
• Pharmaceutical Research & Development: Used in drug metabolism and pharmacokinetics (DMPK) studies to track and quantify metabolites.
• Metabolomics and Biomarker Discovery: Enables accurate profiling of organic acids and related compounds in biological samples.
• Environmental Analysis: Employed in the trace analysis of adipate-based plasticizers or degradation products in environmental samples.
• Polymer Science Research: Serves as a labeled tracer in studies investigating the synthesis, degradation, or migration of polyesters and polyamides.
• Chemical Synthesis: Acts as a deuterated building block for the synthesis of more complex labeled compounds.
