Description

Diphenyl-4,4'-D2 is a deuterated organic compound where two hydrogen atoms on the biphenyl core are replaced by deuterium isotopes. This deuteration is critical for applications requiring precise molecular labeling to study reaction mechanisms, metabolic pathways, and material properties without altering the chemical framework. It is an essential building block and analytical standard for researchers and manufacturers in advanced chemical synthesis and spectroscopic analysis. Key industries that utilize this specialty chemical include pharmaceuticals, agrochemicals, and materials science for developing and testing novel compounds.

Application

• Internal standard in quantitative Mass Spectrometry (MS) and Nuclear Magnetic Resonance (NMR) spectroscopy for accurate analyte measurement.
• Deuterated precursor in the synthesis of labeled pharmaceuticals for drug metabolism and pharmacokinetics (DMPK) studies.
• Tracer compound in reaction mechanism elucidation and catalytic process research within organic chemistry.
• Component in the development of organic electronic materials, such as OLEDs, where deuterium can influence stability and performance.
• Starting material for synthesizing deuterated liquid crystals or polymers for specialized analytical and material science applications.
• Reference standard for ensuring quality control and method validation in analytical laboratory settings.

Quality Control

Every batch of Diphenyl-4,4'-D2 is produced and analyzed under strict quality management protocols to ensure high chemical purity and isotopic enrichment. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) detailing specifications such as isotopic purity (D-enrichment), chemical purity, and identity confirmation are available upon request to support your research and compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent degradation.
