Description

Quinmerac-13C6 CAS NO 1185039-71-7 is a stable isotope-labeled analog of the herbicide quinmerac, where six carbon atoms are replaced with the carbon-13 isotope. This compound is essential as an internal standard for precise and accurate quantitative analysis in advanced mass spectrometry techniques. It is primarily required by analytical laboratories, agrochemical research institutions, and environmental testing facilities for method development, residue analysis, and metabolic studies.

Application

• Internal Standard for LC-MS/MS Analysis: Critical for the accurate quantification of quinmerac residues in complex matrices like soil, water, and plant tissues.
• Metabolic Pathway Research: Used in agrochemical R&D to trace and elucidate the metabolic fate and degradation pathways of quinmerac.
• Environmental Monitoring: Enables reliable detection and measurement of quinmerac levels in environmental samples to assess contamination and compliance.
• Method Development and Validation: Serves as a key reference material for developing, optimizing, and validating sensitive analytical methods in regulatory science.
• Quality Control in Manufacturing: Employed to ensure batch-to-batch consistency and purity in the production of quinmerac-based herbicide formulations.
• Dioxin and Pesticide Analysis: As a labeled standard, it supports high-confidence analysis in multi-residue screening programs for pesticides and related compounds.
