Description

4,4'-Methylene-D2-Dianiline is a deuterated analog of 4,4'-methylenedianiline (MDA), where two hydrogen atoms are replaced with deuterium. This isotopic labeling is crucial for applications requiring enhanced analytical precision and metabolic stability. It serves as a key intermediate and internal standard in advanced research and development, particularly within the pharmaceutical and analytical chemistry sectors.

Application

• Internal standard for the precise quantification of 4,4'-methylenedianiline (MDA) and related compounds in analytical methods like LC-MS and GC-MS.
• Deuterated precursor in the synthesis of labeled polymers, epoxies, and polyurethane materials for research into material properties and degradation pathways.
• Tracer compound in pharmacokinetic, metabolic, and environmental fate studies to track the distribution and breakdown of MDA derivatives.
• Critical reagent in the development and validation of regulatory and forensic testing methodologies.
• Building block for specialty chemicals and advanced materials where isotopic labeling is required for spectroscopic studies.

Quality Control

Every batch of 4,4'-Methylene-D2-Dianiline is produced and analyzed under strict quality management protocols. We ensure high isotopic purity and chemical purity through advanced spectroscopic and chromatographic techniques. A comprehensive Certificate of Analysis (COA) detailing assay, isotopic enrichment, and impurity profile is provided with each shipment to guarantee consistency and reliability for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Recommended long-term storage at 2-8°C. Allow the container to reach room temperature before opening to minimize moisture condensation.
