Description

Coumaphos-Oxon CAS NO 321-54-0 is a key metabolite and degradation product of the organophosphate acaricide coumaphos. This compound is of significant importance in analytical chemistry and environmental monitoring as a primary reference standard. It is essential for researchers and quality control laboratories in the agrochemical, veterinary pharmaceutical, and environmental science sectors who require precise analytical standards for residue analysis, method development, and regulatory compliance testing.

Application

• Primary analytical reference standard for the quantification of coumaphos and its metabolites.
• Critical component in method development and validation for pesticide residue analysis in food and environmental samples.
• Used in quality control and assurance testing for veterinary pharmaceutical formulations containing coumaphos.
• Essential for research studies on the environmental fate, degradation pathways, and ecotoxicology of organophosphate pesticides.
• Calibration standard for advanced analytical instrumentation, including LC-MS/MS and GC-MS systems.
• Supports regulatory compliance testing for agencies monitoring maximum residue limits (MRLs) in animal products and the environment.
