Description

2-Hydroxy-3,7,8-Trichlorodibenzo-4-Dioxin is a halogenated dibenzo-p-dioxin derivative, a compound class of significant interest in chemical research and development. This compound matters as a key synthetic intermediate and reference standard for environmental analysis and toxicological studies. It is primarily needed by research institutions, analytical laboratories, and chemical manufacturers working in the fields of environmental monitoring, persistent organic pollutant (POP) research, and advanced material synthesis.

Application

• Environmental Analytical Standard: Used as a certified reference material (CRM) for the calibration and validation of analytical methods (e.g., GC-MS, HRGC/HRMS) to detect and quantify dioxin and furan congeners in environmental samples.
• Toxicological Research: Serves as a critical reagent in studies investigating the structure-activity relationships (SAR), metabolic pathways, and biological impact of chlorinated dioxins.
• Chemical Synthesis Intermediate: Acts as a specialized building block for the synthesis of more complex dioxin-related compounds or labeled analogs for tracer studies.
• Regulatory Compliance Testing: Employed by industrial and governmental laboratories to ensure compliance with international regulations concerning dioxin emissions and contamination (e.g., Stockholm Convention, EPA methods).
• Method Development & Validation: Essential for developing new, more sensitive, and specific analytical protocols for persistent organic pollutants in complex matrices like soil, water, and biological tissues.
• Quality Control/Assurance: Used as an internal standard or spike in quality control procedures for laboratories performing dioxin analysis to ensure accuracy and precision.
