Description

(-)-Oxy-Chlordane is a specific stereoisomer of the oxychlordane metabolite, a persistent organic pollutant (POP) of significant environmental and analytical interest. This high-purity reference standard is critical for accurate identification, quantification, and toxicological studies of chlordane residues. It is primarily utilized by analytical laboratories, environmental testing facilities, and research institutions engaged in regulatory compliance, environmental monitoring, and forensic analysis.

Application

• Analytical Reference Standard: Primary use as a certified standard for the calibration of GC, GC-MS, and LC-MS/MS systems in environmental and food safety testing.
• Environmental Monitoring: Quantification of oxychlordane, a key bioaccumulative metabolite, in soil, water, sediment, and air samples for pollution assessment.
• Food Safety & Residue Analysis: Detection and measurement of pesticide residues in agricultural products, animal tissues, and dairy to ensure compliance with MRLs (Maximum Residue Limits).
• Toxicological & Metabolic Studies: Research into the environmental fate, biodegradation pathways, and chronic health effects of organochlorine pesticides.
• Forensic and Regulatory Science: Supporting investigations into historical contamination and providing definitive evidence for regulatory enforcement actions.
• Quality Control & Method Development: Used by manufacturers of testing kits and laboratories to validate and optimize analytical methodologies (e.g., EPA methods).

Quality Control

Our (-)-Oxy-Chlordane is produced and handled under strict quality protocols to ensure the highest standard of purity and stability required for analytical applications. Each batch is characterized using advanced techniques including HPLC, GC-MS, and chiral analysis to confirm identity, isomeric purity, and potency. Comprehensive Certificates of Analysis (COA) detailing all test results are provided to guarantee traceability and compliance with your laboratory's quality assurance requirements.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below. Allow the container to reach room temperature in a desiccator before opening to prevent condensation. This material is moisture-sensitive (hygroscopic).
