Description

2-Aminonaphthalene (Ring-D7,98%) is a deuterium-labeled derivative of 2-naphthylamine, where seven hydrogen atoms on the aromatic rings have been replaced with deuterium atoms, achieving a chemical purity of 98%. This isotopic labeling is critical for creating internal standards in mass spectrometry, enhancing analytical accuracy and reliability. It is an essential material for researchers and quality control laboratories in the pharmaceutical, environmental testing, and forensic science industries who require precise quantification and metabolic pathway tracing.

Application

• Internal Standard for Mass Spectrometry (MS): Serves as a critical quantitative reference in LC-MS and GC-MS analysis for unlabeled 2-aminonaphthalene and related compounds.
• Pharmaceutical Research & Metabolism Studies: Used in pharmacokinetic and drug metabolism studies to track and quantify metabolites with high precision.
• Environmental and Food Safety Analysis: Enables accurate detection and measurement of naphthylamine derivatives as potential contaminants or residues.
• Forensic Toxicology: Supports the precise identification and quantification of specific amine compounds in complex biological matrices.
• Chemical Synthesis & Deuterium Labeling: Acts as a building block for synthesizing more complex deuterated molecules for research and development.
• Academic and Industrial R&D: Facilitates advanced research in organic chemistry, material science, and analytical method development.
