Description

3-Phenoxy-13C6-Benzoic Acid is a stable isotope-labeled analog of 3-phenoxybenzoic acid, where six carbon atoms are replaced with the 13C isotope. This compound is essential as a critical internal standard and reference material in advanced analytical chemistry, enabling precise quantification and method validation. It is primarily needed by analytical laboratories, agrochemical manufacturers, and environmental testing facilities engaged in high-accuracy mass spectrometry (LC-MS/MS, GC-MS) for trace analysis of metabolites and environmental pollutants.

Application

• Internal Standard for Mass Spectrometry: Used as a quantitative reference in LC-MS/MS and GC-MS analysis for 3-phenoxybenzoic acid and related compounds.
• Agrochemical Metabolite Studies: Critical for tracing and quantifying the environmental fate and metabolic pathways of pyrethroid insecticides.
• Environmental Monitoring: Enables accurate detection and measurement of pesticide residues in water, soil, and food samples.
• Clinical & Forensic Toxicology: Supports method development for detecting specific biomarkers or toxicants in biological matrices.
• Pharmaceutical Research: Serves as a labeled precursor or metabolite standard in drug metabolism and pharmacokinetics (DMPK) studies.
• Method Development & Validation: Provides a certified reference material to establish accuracy, precision, and calibration curves in analytical methods.
• Regulatory Compliance Testing: Supports testing protocols required by agencies like the EPA for environmental safety assessments.
