Description

12-Methylbenzo[A]Pyrene is a methylated derivative of the well-characterized polycyclic aromatic hydrocarbon (PAH), Benzo[a]pyrene. This compound is of significant interest in research and analytical chemistry as a high-purity reference standard for environmental monitoring, toxicology studies, and method development. It serves as a critical material for scientists and quality control laboratories requiring precise calibration standards for the analysis of complex PAH mixtures. Target users include environmental testing facilities, academic research institutions, and industrial laboratories focused on petrochemical analysis, food safety, and occupational health.

Application

• Analytical Reference Standard: Primary use as a certified reference material (CRM) for calibrating instruments like GC-MS and HPLC in PAH analysis.
• Environmental Monitoring: Calibration and quality control for testing soil, water, and air samples for PAH contamination from industrial processes or combustion.
• Toxicological Research: Used in studies to understand the metabolic pathways, mutagenicity, and carcinogenicity of methylated PAHs compared to their parent compounds.
• Method Development & Validation: Essential for developing, optimizing, and validating new analytical methods for the separation and quantification of PAHs.
• Food Safety Testing: Employed in the analysis of PAHs in food products, particularly for smoked, grilled, or roasted items, to ensure regulatory compliance.
• Occupational Health & Safety: Calibration standard for monitoring workplace air in industries like aluminum production, coke plants, and tar distillation.
• Petrochemical & Fuel Analysis: Used to characterize the PAH profile in crude oil, refined fuels, and lubricants.
• Pharmaceutical Impurity Profiling: Potential use as a standard for detecting and quantifying PAH impurities in active pharmaceutical ingredients (APIs) or excipients derived from mineral sources.

Quality Control

Every batch of 12-Methylbenzo[A]Pyrene is produced and controlled under a strict quality management system. We employ advanced chromatographic techniques to ensure high chemical purity and identity confirmation. Certificates of Analysis (COA) are provided with each shipment, detailing key parameters such as assay purity, identity by spectroscopic methods, and impurity profiles. Our quality standards are designed to meet the rigorous demands of analytical and research applications.

Storage

Preserve in a tightly closed container, protected from light. Store at controlled room temperature (15-25°C) in a cool, dry, and well-ventilated place. Due to its light-sensitive and easily oxidized nature, prolonged exposure to light and air should be avoided. For long-term storage, consider keeping the container under an inert atmosphere such as argon or nitrogen.
