Description

Benzidine-D8 CAS NO 92890-63-6 is a deuterium-labeled internal standard of the aromatic amine benzidine, essential for precise quantitative analysis. This isotopically labeled compound is critical for ensuring accuracy and reliability in sensitive analytical techniques, particularly in regulated environments. It is primarily used by analytical chemists and researchers in pharmaceutical, environmental, and forensic laboratories for method development and validation.

Application

• Internal Standard for Mass Spectrometry (MS): Used as a quantitative reference in LC-MS/MS and GC-MS analysis to correct for instrument variability and sample preparation losses.
• Metabolite and Biomarker Studies: Enables the tracking and quantification of benzidine and its metabolites in pharmacokinetic and toxicological research.
• Environmental Monitoring: Critical for the accurate detection and quantification of trace levels of benzidine, a regulated environmental contaminant, in water and soil samples.
• Forensic and Doping Control Analysis: Provides high-confidence results in confirmatory testing where precise quantification is legally required.
• Method Development and Validation: Serves as a key component in establishing robust, accurate, and compliant analytical methods according to FDA, EPA, or ICH guidelines.
• Quality Control in Chemical Manufacturing: Used to monitor for the presence of benzidine impurities in chemical synthesis processes.

Quality Control

Our Benzidine-D8 is manufactured under strict quality systems to ensure the high isotopic purity and chemical stability required for analytical applications. Each batch is characterized by advanced spectroscopic and chromatographic methods, including NMR and HPLC, to confirm identity, isotopic enrichment (typically ≥98 atom % D), and chemical purity. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

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. Keep the container sealed to prevent moisture absorption and contamination.
