Description

7,8-Dihydro-7,8-Dihydroxy-5-Methylchrysene is a high-purity, polycyclic aromatic hydrocarbon (PAH) derivative of significant interest in advanced chemical research and development. This compound serves as a critical intermediate or reference standard for studying metabolic pathways, environmental analysis, and toxicological profiles of PAHs. It is primarily required by research institutions, analytical laboratories, and pharmaceutical R&D departments engaged in carcinogenicity studies, biomarker discovery, and the synthesis of specialized chemical probes.

Application

• Biochemical and Toxicological Research: Used as a key intermediate or metabolite standard in studies investigating the carcinogenic mechanisms and metabolic activation pathways of methylated chrysenes.
• Analytical Reference Standard: Serves as a high-purity calibrant or internal standard in chromatographic (HPLC, GC-MS) methods for the quantification of PAH derivatives in complex matrices.
• Environmental Science: Employed in method development and validation for tracing and analyzing hydroxylated PAH metabolites in environmental and biological samples.
• Pharmaceutical Development: Acts as a building block or a metabolite analog in the synthesis of compounds for pharmacological evaluation and drug metabolism studies.
• Material Science Research: Investigated as a precursor or a model compound in the development of organic semiconductors or advanced polymeric materials due to its fused aromatic structure.

Quality Control

Our 7,8-Dihydro-7,8-Dihydroxy-5-Methylchrysene is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity for research applications. Each lot undergoes comprehensive analytical characterization, including HPLC for purity assay and spectroscopic identification (NMR, IR). A detailed Certificate of Analysis (COA) documenting identity, purity, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider desiccants or an inert atmosphere.
