Description

trans-Chlordane is a specific stereoisomer of the organochlorine compound chlordane, a substance of significant historical and research importance. Its well-defined chemical structure makes it a critical reference standard and analytical tool for environmental monitoring and regulatory compliance. This product is essential for laboratories and research institutions focused on legacy pesticide analysis, environmental fate studies, and method development. We supply high-purity trans-Chlordane CAS NO 5103-74-2 to support rigorous scientific and analytical work.

Application

• Environmental Analysis Reference Standard: Primary use as a certified reference material (CRM) or analytical standard for the quantification of chlordane isomers in soil, water, and biota samples.
• Pesticide Residue Testing: Critical for calibrating equipment and validating methods in food safety and agricultural product testing laboratories to detect trace contaminants.
• Toxicological and Ecotoxicological Research: Used in studies investigating the long-term environmental persistence, bioaccumulation, and toxic effects of organochlorine pesticides.
• Forensic and Regulatory Science: Supports investigations into chemical contamination sources and compliance testing against international bans and restrictions (e.g., Stockholm Convention).
• Method Development and Validation: Serves as a key component in developing and verifying new analytical techniques such as GC-MS or GC-ECD for complex matrices.
• Quality Control/Quality Assurance (QC/QA): Employed in laboratory proficiency testing and internal quality control programs to ensure accuracy and reliability of analytical data.
