Description

4-n-Butyl-D9-Aniline is a high-purity, deuterium-labeled analog of n-butyl aniline, serving as a critical internal standard and tracer in advanced analytical chemistry. Its primary value lies in enabling precise quantification and metabolic pathway elucidation through mass spectrometry, eliminating interference from endogenous compounds. This stable isotope-labeled compound is essential for researchers and quality control laboratories in the pharmaceutical, agrochemical, and environmental testing industries who require uncompromised accuracy in method development and regulatory analysis.

Application

• Pharmaceutical Research & Development: Used as a stable isotope-labeled internal standard in LC-MS/MS and GC-MS for the accurate bioanalysis and pharmacokinetic study of drug candidates and their metabolites.
• Metabolomics and Biomarker Discovery: Enables precise tracking and quantification of amine-containing metabolites in complex biological samples.
• Agrochemical Analysis: Serves as a reference standard for the detection and quantification of aniline-based pesticides, herbicides, and their degradation products in environmental and food safety testing.
• Chemical Synthesis Intermediary: Acts as a deuterated building block for the synthesis of more complex labeled compounds for research purposes.
• Forensic and Doping Control: Provides a reliable standard for the confirmatory analysis of specific substances in forensic toxicology and anti-doping programs.
• Quality Control & Method Validation: Critical for developing and validating robust analytical methods in compliance with ICH, FDA, and EPA guidelines.
