Description

cis-Nonachlor CAS NO 5103-73-1 is a specific stereoisomer of the organochlorine compound nonachlor, known for its persistence and bioaccumulative properties. This compound is of significant interest in environmental analysis and research, serving as a critical reference standard and marker for historical pesticide contamination studies. It is primarily required by analytical laboratories, environmental testing facilities, and research institutions focused on persistent organic pollutants (POPs), legacy pesticide analysis, and ecological risk assessment.

Application

• Primary use as an analytical reference standard for the calibration of GC-MS, GC-ECD, and HPLC systems in environmental testing.
• Critical component in method development and validation for the detection and quantification of organochlorine pesticide residues in soil, water, and biological samples.
• Essential for quality control and proficiency testing in commercial and regulatory environmental laboratories to ensure analytical accuracy.
• Used in scientific research investigating the environmental fate, transport, and toxicological profile of chiral organochlorine compounds.
• Employed in forensic environmental chemistry to fingerprint contamination sources and study historical pesticide use patterns.
• Serves as a teaching tool in advanced university chemistry and environmental science programs for chromatographic separation of isomers.

Quality Control

Every batch of our cis-Nonachlor is produced and handled under strict quality protocols to ensure identity, purity, and stability for analytical applications. We provide comprehensive Certificates of Analysis (COA) that detail chromatographic purity, isomer specificity, and confirmatory spectroscopic data. Our quality systems are designed to meet the rigorous demands of ISO/IEC 17025 accredited laboratories and research institutions requiring traceable and reliable reference materials.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its light-sensitive nature, the container should be amber-colored or stored in opaque secondary packaging. Keep away from heat and incompatible materials.
