Description

2-Aminodiphenyl-D9 is a deuterium-labeled isotopologue of 2-aminobiphenyl, a compound of significant importance in analytical chemistry and life sciences research. Its primary value lies in its use as a stable internal standard for mass spectrometry, enabling precise quantification and improving the accuracy of analytical methods. This high-purity labeled compound is essential for researchers and quality control laboratories in the pharmaceutical, environmental testing, and forensic science industries who require reliable standards for method development and validation.

Application

• Used as a stable isotope-labeled internal standard (SIL-IS) for the accurate quantification of 2-aminobiphenyl and related aromatic amines via LC-MS/MS and GC-MS.
• Critical for pharmaceutical research and development, particularly in metabolism studies, pharmacokinetic analysis, and impurity profiling of drug substances.
• Applied in environmental and industrial hygiene monitoring for the trace analysis of potentially hazardous aromatic amines in air, water, and soil samples.
• Facilitates forensic and toxicological analysis, providing a reference for detecting and measuring specific amine compounds in complex biological matrices.
• Supports material science research involving deuterated compounds and the study of isotopic effects in chemical reactions.
• Enables quality control and regulatory compliance testing in industries where monitoring for specific amine contaminants is required.
