Description

Heptachlor is a chlorinated cyclodiene insecticide with the CAS registry number 76-44-8. This compound is historically significant for its potent and persistent pesticidal activity, offering long-term protection against a range of soil-dwelling and foliar pests. It is primarily sought by researchers, environmental testing laboratories, and chemical manufacturers for analytical reference standards, environmental fate studies, and as a precursor in specialized chemical synthesis.

Application

• Analytical Reference Standard: Used as a certified standard in gas chromatography (GC) and mass spectrometry (MS) for the quantification of pesticide residues in environmental and food safety testing.
• Environmental Research: Critical for studies on the persistence, bioaccumulation, and degradation pathways of organochlorine pesticides in soil and water systems.
• Chemical Intermediate: Serves as a key starting material or intermediate in the synthesis of other organochlorine compounds for research purposes.
• Historical Formulation Analysis: Employed in forensic and regulatory science to identify and quantify legacy contaminants in archived samples.

Quality Control

Our Heptachlor is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and traceability. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity confirmation, and impurity profiles, typically verified by HPLC, GC, and spectroscopic methods. We support compliance with global regulatory frameworks for analytical standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. Due to its chemical nature, it should be stored separately from strong oxidizers and bases.
