Description

p-Toluidine-D3 (Methyl-D3) is a deuterium-labeled derivative of p-toluidine, where three hydrogen atoms on the methyl group are replaced with deuterium. This isotopic labeling is critical for applications requiring internal standards in mass spectrometry, enabling precise quantification and reliable analytical results. It is an essential compound for research and quality control laboratories in the pharmaceutical, agrochemical, and environmental testing sectors, where accurate trace analysis is paramount.

Application

• Internal Standard for LC-MS/MS and GC-MS analysis in pharmaceutical research and bioanalytical studies.
• Deuterated reference material for metabolite identification and drug metabolism studies (DMPK).
• Tracer compound in environmental fate studies and pollutant degradation research.
• Isotopic diluent for the accurate quantification of p-toluidine and related compounds in complex matrices.
• Precursor in the synthesis of deuterium-labeled dyes, pigments, and advanced materials.
• Use in NMR spectroscopy as a tool for mechanistic and structural elucidation studies.

Quality Control

Our deuterated compounds are produced under strict quality protocols to ensure high isotopic purity and chemical integrity, essential for reliable analytical results. Each batch is characterized by NMR and mass spectrometry to confirm deuteration level and chemical purity. Certificates of Analysis (COA) detailing isotopic enrichment (e.g., D% > 98 atom % D), chemical purity, and analytical methods are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to minimize exposure to atmospheric moisture.
