Description

trans-Nonachlor CAS NO 39765-80-5 is a specific stereoisomer of the chlorinated hydrocarbon insecticide nonachlor, known for its persistence and bioaccumulative properties. This compound is of significant interest in environmental science and analytical chemistry, primarily as a reference standard and a marker for historical pesticide contamination. It is essential for researchers, analytical laboratories, and environmental monitoring agencies involved in the study of legacy organochlorine pollutants. Its precise characterization is critical for accurate risk assessment and regulatory compliance in soil and water analysis.

Application

• Environmental Analysis Reference Standard: Primary use as an analytical standard for the quantification of nonachlor isomers and other organochlorine pesticides (OCPs) in environmental samples via GC-MS or GC-ECD.
• Ecological and Toxicological Research: Serves as a key compound in studies investigating the environmental fate, bioaccumulation, and toxicological effects of persistent organic pollutants (POPs).
• Soil and Groundwater Contamination Assessment: Used to calibrate equipment and validate methods for monitoring legacy pesticide residues at contaminated industrial or agricultural sites.
• Food Safety Testing: Employed as a calibration standard in laboratories testing for pesticide residues in food products to ensure compliance with international safety regulations.
• Quality Control for Manufacturing: Acts as a purity reference in the chemical industry for producers of pesticide mixtures or related chlorinated compounds.
• Regulatory Compliance and Method Development: Essential for developing and certifying analytical methods required by agencies like the EPA for environmental protection.
