Description

3,3-Dichlorobenzidine-13C12 is a stable isotope-labeled analog of 3,3'-dichlorobenzidine, where all twelve carbon atoms are the carbon-13 isotope. This compound is essential as an internal standard for precise quantitative analysis in mass spectrometry, ensuring accurate and reliable results. It is primarily needed by analytical laboratories, environmental testing facilities, and research institutions conducting trace-level detection and metabolic studies of benzidine derivatives.

Application

• Internal Standard for LC-MS/MS: Used for the accurate quantification of 3,3'-dichlorobenzidine and related compounds in complex matrices.
• Environmental Analysis: Critical for tracing and measuring benzidine-based dye pollutants in soil and water samples.
• Metabolic Pathway Research: Enables the study of the biotransformation and fate of dichlorobenzidine in biological systems.
• Forensic Toxicology: Supports the detection and confirmation of specific aromatic amine exposures.
• Pharmaceutical Impurity Profiling: Aids in the sensitive detection of genotoxic impurities during drug substance development.
• Quality Control in Dye Manufacturing: Serves as a reference standard for monitoring residual precursors in final products.

Quality Control

Our 3,3-Dichlorobenzidine-13C12 is manufactured under controlled conditions to ensure high isotopic purity and chemical integrity. Each batch undergoes rigorous analysis, including HPLC, NMR, and mass spectrometry, to confirm isotopic enrichment and chemical purity. Certificates of Analysis (COA) detailing isotopic purity, chemical purity, and solvent content are available upon request.

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 hygroscopic nature, the container should be kept in a desiccated environment to prevent moisture absorption. Handle and store in accordance with all applicable regulations for laboratory chemicals.
