Description

4,4'-Ddt CAS NO 50-29-3 is a high-purity organochlorine compound, also known as p,p'-DDT, serving as a critical reference standard and research chemical. Its primary value lies in providing a definitive benchmark for analytical testing, environmental monitoring, and regulatory compliance in legacy contamination studies. This product is essential for laboratories and industries involved in pesticide analysis, environmental science, and the development of detection methodologies.

Application

• Analytical Reference Standard: Primary use as a certified standard for calibrating equipment (GC, GC-MS, HPLC) in quantitative and qualitative analysis.

• Environmental Monitoring & Research: Critical for testing soil, water, and biological samples for persistent organic pollutant (POP) residues and studying environmental fate and transport.

• Method Development & Validation: Used by analytical laboratories to develop, optimize, and validate testing protocols for organochlorine pesticides.

• Quality Control & Assurance: Serves as an internal control standard in manufacturing and testing facilities to ensure analytical accuracy.

• Regulatory Compliance Testing: Employed to verify compliance with international regulations (e.g., Stockholm Convention, EPA methods) regarding banned or restricted substances.
