Description

8,9,11-Trimethylbenz[A]Anthracene Standard Solution is a high-purity, certified reference material (CRM) used for analytical calibration and quality control. This solution is critical for ensuring the accuracy and reliability of chromatographic and spectroscopic analyses in research and regulatory testing. It is primarily needed by analytical laboratories, environmental testing facilities, and pharmaceutical R&D departments engaged in polycyclic aromatic hydrocarbon (PAH) analysis and method validation.

Application

• Analytical Reference Standard: Primary use as a certified standard for calibrating HPLC, GC-MS, and LC-MS instruments in quantitative analysis.
• Environmental Monitoring: Used in the testing of soil, water, and air samples for PAH contamination to meet regulatory compliance (e.g., EPA methods).
• Pharmaceutical Research: Serves as a precise reference compound in metabolic studies, impurity profiling, and stability testing of drug substances.
• Food Safety Testing: Employed as a calibration standard in the analysis of PAHs in food products, such as grilled meats and oils, to ensure safety standards.
• Toxicology Studies: Used as a well-defined agent in research investigating the carcinogenic and mutagenic properties of methylated PAHs.
• Method Development & Validation: Essential for developing, verifying, and accrediting new analytical methods in compliance with ISO/IEC 17025.
• Quality Assurance/Quality Control (QA/QC): Provides a benchmark for internal and external laboratory proficiency testing and inter-laboratory comparisons.
