Description

Benzo[A]Pyrene-7-D is a deuterated isotopologue of the well-characterized polycyclic aromatic hydrocarbon (PAH), benzo[a]pyrene. This labeled compound is essential for providing an internal standard in advanced analytical techniques, ensuring precise quantification and method validation. It is a critical reagent for researchers and quality control laboratories in the environmental, pharmaceutical, and toxicology sectors who require high-fidelity analytical standards for trace-level analysis.

Application

• Internal Standard for Mass Spectrometry (MS): Serves as a crucial quantitative reference in GC-MS or LC-MS/MS analysis of PAHs in complex matrices.
• Environmental Analysis: Used in the accurate measurement of benzo[a]pyrene and other PAHs in soil, water, and air particulate matter for regulatory compliance and pollution studies.
• Metabolic and Toxicological Research: Enables the tracking of specific metabolic pathways and DNA adduct formation studies of benzo[a]pyrene in biological systems.
• Pharmaceutical Impurity Profiling: Acts as a reference standard in the analysis of potential genotoxic impurities in active pharmaceutical ingredients (APIs) and finished drug products.
• Food Safety Testing: Employed in the quantification of carcinogenic PAHs in food products, such as smoked meats and oils, to ensure consumer safety.
• Method Development and Validation: Provides a stable, isotopically labeled standard to establish accuracy, precision, and recovery rates in new analytical protocols.

Quality Control

Every batch of Benzo[A]Pyrene-7-D is manufactured and analyzed under strict quality management systems to ensure identity, purity, and isotopic enrichment meet the exacting requirements for analytical standards. We provide comprehensive Certificates of Analysis (COA) detailing results for assay, isotopic purity, and related substance analysis via techniques like HPLC and NMR. Our quality commitment supports compliance with relevant guidelines for reference materials.

Storage

Preserve in a tightly closed container, protected from light. Store at controlled room temperature (15-25°C) or as indicated on the label or COA. Due to its light-sensitive nature and potential for oxidation, prolonged exposure to light and air should be avoided. For long-term storage, consider under an inert atmosphere.
