Description

Benzo[e]pyrene CAS NO 192-97-2 is a high-purity polycyclic aromatic hydrocarbon (PAH) of significant interest in research and industrial applications. This compound is a critical reference standard and a key intermediate in the study of environmental pollutants, material science, and chemical synthesis. It is primarily utilized by analytical laboratories, environmental testing facilities, and research institutions focused on toxicology, combustion chemistry, and advanced material development.

Application

• Analytical Reference Standard: Used as a certified reference material (CRM) for the calibration and validation of analytical instruments (HPLC, GC-MS) in environmental and food safety testing.
• Environmental Research: Serves as a model compound in studies of PAH formation, transport, degradation, and toxicological impact in soil, water, and air.
• Toxicology & Carcinogenicity Studies: Employed in biochemical and pharmacological research to investigate the mechanisms of PAH-induced toxicity and metabolic pathways.
• Material Science Research: Acts as a precursor or dopant in the development of organic semiconductors, carbon-based nanomaterials, and optoelectronic devices.
• Combustion & Fuel Analysis: Used to analyze and quantify PAH emissions from various combustion processes and fossil fuels.
• Regulatory Compliance Testing: Essential for laboratories conducting testing to comply with international regulations (e.g., EPA, EU) concerning PAH limits in consumer products, rubber, plastics, and contaminated sites.

Quality Control

Every batch of Benzo[e]pyrene is manufactured and tested under strict quality management protocols. Our standard grade meets high-purity specifications suitable for research and analytical applications, with identity and purity verified by chromatographic and spectroscopic methods. A comprehensive Certificate of Analysis (COA) detailing batch-specific results for assay, related substances, and identification is provided with each shipment. Custom purification to meet specific research or compendial standards (e.g., for certified reference materials) is available upon request.

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 and easily oxidized nature, prolonged exposure to light and air should be avoided. For long-term storage, consider sealing under an inert atmosphere such as argon or nitrogen.
