Description

4,4'-Di(Methyl-D)-1,1'-Biphenyl is a deuterated organic compound where hydrogen atoms on the methyl groups are replaced by deuterium. This isotopic labeling is critical for applications requiring enhanced molecular stability, precise analytical tracking, or altered reaction kinetics. It serves as a valuable intermediate and reference standard in advanced research and development sectors, particularly where deuterium's unique nuclear properties are leveraged.

Application

• Pharmaceutical Research & Development: Used as a deuterated building block or internal standard in the synthesis and analysis of novel drug candidates, aiding in metabolism studies (DMPK) and patent strategies.
• Analytical Chemistry: Serves as a critical reference standard in mass spectrometry (MS) and nuclear magnetic resonance (NMR) spectroscopy for method calibration and quantitative analysis.
• Organic Electronics & Material Science: Acts as a precursor or dopant in the development of organic light-emitting diodes (OLEDs) and other advanced materials where deuterium substitution can improve device lifetime and performance.
• Deuterated Solvent & Reagent Production: Employed in the synthesis of more complex deuterated solvents and specialty reagents for spectroscopic applications.
• Mechanistic Studies: Utilized in kinetic isotope effect (KIE) studies to investigate reaction mechanisms and pathways in catalytic and synthetic chemistry.

Quality Control

Every batch of our 4,4'-Di(Methyl-D)-1,1'-Biphenyl is manufactured and tested under strict quality management systems. We provide comprehensive analytical data to ensure product identity, purity, and isotopic enrichment meet the exacting requirements of research and industrial applications. A detailed Certificate of Analysis (COA) including results for assay, isotopic purity (D-content), and impurity profile is available for each lot upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to minimize exposure to atmospheric moisture. For long-term storage, consider using desiccants or an inert atmosphere.
