Description

β-Heptachlorepoxide is a specific stereoisomer of heptachlor epoxide, a compound of significant interest in chemical research and analytical chemistry. Its primary value lies in its use as a high-purity reference standard for environmental monitoring and toxicological studies. This product is essential for laboratories and industries requiring precise analytical calibration, particularly in the fields of environmental testing, regulatory compliance, and agrochemical research.

Application

• Analytical Reference Standard: Primary use as a certified standard for gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) in environmental analysis.
• Environmental Monitoring: Calibration and quantification of heptachlor epoxide isomers in soil, water, and air samples to assess pollution levels.
• Toxicology and Metabolism Studies: Used in research to study the environmental persistence, metabolic pathways, and toxicological profile of organochlorine pesticides.
• Quality Control and Method Development: Serves as a critical component in developing and validating analytical methods for pesticide residue testing in compliance with global regulations.
• Regulatory and Forensic Analysis: Employed by government and commercial labs for forensic analysis and to ensure compliance with environmental protection standards (e.g., EPA, EU directives).
• Research and Development: Used in academic and industrial R&D for synthesizing derivatives or studying the chemical behavior of chlorinated epoxides.

Quality Control

Our β-Heptachlorepoxide is manufactured and handled under strict quality protocols to ensure the highest purity and batch-to-batch consistency required for analytical applications. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity confirmation, and impurity profiles. We adhere to relevant industry standards for reference materials, and our QC procedures include rigorous chromatographic and spectroscopic verification (HPLC, GC, GC-MS, NMR) to meet the exacting demands of research and compliance laboratories.

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 kept in secondary packaging or a dark storage cabinet. For long-term stability, consider storage under inert atmosphere.
