Description

4-Aminodiphenyl-D9 is a deuterium-labeled analog of 4-aminodiphenyl, a compound of significant interest in analytical and research chemistry. This stable isotope-labeled standard is essential for ensuring accuracy and reliability in quantitative mass spectrometry analyses, where it serves as an internal standard to correct for variations in sample preparation and instrument response. It is primarily utilized by analytical laboratories, contract research organizations (CROs), and pharmaceutical R&D departments engaged in metabolism studies, environmental monitoring, and the development of sensitive detection methods for aromatic amines.

Application

• Internal Standard for LC-MS/MS: Used as a quantitative reference standard in liquid chromatography-tandem mass spectrometry for the precise analysis of 4-aminodiphenyl and related compounds.
• Metabolite Tracing in Pharmacokinetics: Enables accurate tracking and quantification of drug metabolites in biological matrices during ADME (Absorption, Distribution, Metabolism, and Excretion) studies.
• Environmental Analysis: Serves as a critical standard in the detection and quantification of aromatic amine pollutants in water, soil, and industrial waste samples.
• Occupational Health & Safety Monitoring: Facilitates the accurate measurement of 4-aminodiphenyl exposure in workplace air or biological monitoring programs.
• Certified Reference Material (CRM): Can be characterized for use as a high-purity certified reference material to validate analytical methods and ensure laboratory compliance.
• Stable Isotope Dilution Assays: Employed in isotope dilution techniques to achieve superior accuracy and precision in complex sample analysis.
