Description

7-Acetoxymethylbenz[A]Anthracene-13C is a stable isotope-labeled derivative of a polycyclic aromatic hydrocarbon (PAH), specifically incorporating a carbon-13 atom at a key molecular position. This compound is of significant value as a high-purity internal standard and tracer in advanced analytical and metabolic research. It is primarily required by analytical laboratories, contract research organizations (CROs), and pharmaceutical R&D teams engaged in mass spectrometry, environmental analysis, and studies of PAH metabolism and carcinogenesis.

Application

• Internal Standard for Mass Spectrometry (MS): Provides precise quantification in LC-MS and GC-MS analysis of benz[a]anthracene and its metabolites, correcting for instrument variability and sample loss.
• Metabolic Pathway Tracing: Used in pharmacokinetic and toxicological studies to track the biotransformation and distribution of benz[a]anthracene derivatives in biological systems.
• Environmental Analysis: Enables accurate measurement of PAH contaminants in complex matrices like soil, water, and air particulates through isotope dilution techniques.
• Biomarker Research: Facilitates the development and validation of assays for PAH-DNA adducts and other exposure biomarkers.
• Pharmaceutical Impurity Profiling: Serves as a reference standard in the analysis of potential genotoxic impurities in drug substances and products.
• Chemical Synthesis Intermediate: Acts as a labeled building block for the synthesis of more complex 13C-labeled compounds for research purposes.
