Description

4-Nitropyrene is a high-purity polycyclic aromatic hydrocarbon (PAH) derivative, widely recognized as a critical intermediate and reference standard in advanced chemical research and development. Its significance lies in its role as a model compound for studying nitrated PAHs, which are important environmental contaminants and subjects of toxicological investigation. This product is essential for researchers and quality control laboratories in the environmental monitoring, analytical chemistry, and material science sectors seeking reliable and well-characterized chemical standards.

Application

• Environmental Analysis Standard: Used as a certified reference material (CRM) for the calibration and validation of analytical methods (e.g., GC-MS, HPLC) detecting nitrated polycyclic aromatic hydrocarbons (Nitro-PAHs) in air, soil, and water samples.
• Toxicological Research: Serves as a key compound in studies investigating the mutagenicity, carcinogenicity, and metabolic pathways of nitro-PAHs.
• Chemical Synthesis Intermediate: Acts as a precursor for the synthesis of more complex PAH derivatives, dyes, and functional organic materials.
• Occupational Health & Safety: Employed in the development and testing of monitoring equipment and protocols for workplaces exposed to diesel exhaust and other combustion-related pollutants.
• Pharmaceutical Impurity Profiling: Utilized in method development for detecting and quantifying potentially genotoxic impurities in active pharmaceutical ingredients (APIs).
• Fuel & Combustion Research: Applied as a marker compound in studies analyzing the formation and emission profiles of nitro-PAHs from various fuel sources.

Quality Control

Every batch of 4-Nitropyrene is manufactured and analyzed under a strict quality management system to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) detailing results from advanced analytical techniques including HPLC, GC-MS, and NMR. Our quality protocols are designed to meet the rigorous demands of reference standard and research-grade chemical applications.

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 and propensity to be easily oxidized, it is recommended to store the material under an inert atmosphere for long-term preservation and to minimize exposure to air and moisture upon opening.
