Description

2,3-Diaminotoluene-D3 is a deuterium-labeled isotopologue of the aromatic diamine 2,3-diaminotoluene, specifically designed for use as an internal standard in analytical chemistry. This compound matters because it provides the essential isotopic purity and stability required for accurate quantification in sophisticated mass spectrometry and NMR-based methods, eliminating matrix effects and ensuring reliable data. It is critically needed by researchers and quality control laboratories in the pharmaceutical, agrochemical, and environmental testing industries for method development, pharmacokinetic studies, and metabolite identification.

Application

• Internal Standard for LC-MS/MS: Primary application for the precise quantification of 2,3-diaminotoluene and related compounds in complex biological and environmental matrices.
• Pharmaceutical Research: Used in drug metabolism and pharmacokinetics (DMPK) studies to track the absorption, distribution, metabolism, and excretion of parent compounds.
• Metabolite Identification: Aids in the structural elucidation of metabolites in biomedical and toxicological research.
• Agrochemical Analysis: Enables accurate residue testing of pesticides or herbicides where 2,3-diaminotoluene is a metabolite or degradation product.
• Environmental Monitoring: Employed in the analysis of water and soil samples for pollutants derived from toluene diamines.
• Polymer Research: Serves as a tracer in studies on the synthesis and degradation mechanisms of polyurethanes and other polymers.
• Forensic Toxicology: Supports the confirmatory analysis of specific compounds in forensic investigations.
