Description

Diphenyl-D5-Methanol is a deuterated organic compound where five hydrogen atoms in the phenyl rings are replaced by deuterium, a stable hydrogen isotope. This isotopic labeling is critical for applications requiring precise molecular tracking and reduced metabolic interference in research environments. It serves as a valuable intermediate and analytical standard for pharmaceutical development, agrochemical research, and advanced material science. The compound is particularly essential for scientists and manufacturers engaged in deuterium-labeled synthesis, mass spectrometry, and NMR spectroscopy.

Application

• Pharmaceutical Research & Development: Used as a key deuterated building block in the synthesis of novel Active Pharmaceutical Ingredients (APIs) for drug discovery and metabolic studies.
• Analytical Chemistry Standards: Serves as an internal standard or reference material in quantitative analysis via Liquid Chromatography-Mass Spectrometry (LC-MS) and Gas Chromatography-Mass Spectrometry (GC-MS).
• Agrochemical Innovation: Employed in the development and tracing of deuterated agrochemicals to study environmental fate, metabolism, and efficacy.
• NMR Spectroscopy Solvent/Probe: Utilized in nuclear magnetic resonance (NMR) spectroscopy due to its deuterium content, aiding in solvent signal suppression and detailed molecular structure analysis.
• Material Science Research: Acts as a precursor or modifier in the development of specialty polymers and organic electronic materials where isotopic purity affects performance.
• Metabolic Pathway Tracing: Facilitates the study of biochemical pathways and pharmacokinetics in vivo using deuterium as a non-radioactive tracer.

Quality Control

Our Diphenyl-D5-Methanol is produced under strict quality management protocols to ensure high isotopic and chemical purity for sensitive research applications. Each batch is characterized by advanced analytical techniques including NMR, HPLC, and Mass Spectrometry. A comprehensive Certificate of Analysis (COA) detailing purity, isotopic enrichment (D-atom %), and impurity profiles is provided with every shipment to guarantee traceability and compliance with your project specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled 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) after opening to prevent degradation.
