Description

Diphenyl-D5-Methyl Alcohol (Phenyl-D5) is a deuterated organic compound where five hydrogen atoms on the phenyl rings are replaced by deuterium. This high-purity labeled compound is critical for applications requiring precise analytical tracking and minimal background interference. It is primarily utilized by researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors for use as an internal standard, a tracer in metabolic studies, and a building block in the synthesis of deuterated active pharmaceutical ingredients (APIs).

Application

• Internal Standard for Quantitative Analysis (GC-MS, LC-MS)
• Deuterated Tracer in Pharmacokinetic and Metabolic Studies
• Key Synthetic Intermediate for Deuterated Active Pharmaceutical Ingredients (APIs)
• Building Block in Organic Synthesis for Specialty Chemicals
• NMR Solvent and Reagent for Structural Analysis
• Research and Development of Novel Deuterated Materials

Quality Control

Our Diphenyl-D5-Methyl Alcohol is produced under strict quality management systems to ensure exceptional isotopic and chemical purity. Each batch undergoes comprehensive analytical testing, including NMR, GC-MS, and HPLC, to verify deuterium enrichment and chemical identity. A detailed Certificate of Analysis (COA) specifying isotopic purity (e.g., D atom %), chemical purity, and residual solvent levels is provided with every shipment to support your research and compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent exposure to atmospheric moisture.
