Description

m-Tolunitrile-D7 is a deuterated isotopologue of m-tolunitrile, where seven hydrogen atoms are replaced with deuterium, serving as a stable, non-radioactive isotopic label. This high-purity compound is critical for applications requiring precise internal standards in quantitative mass spectrometry, eliminating interference from endogenous compounds. It is primarily utilized by analytical chemists and researchers in the pharmaceutical, agrochemical, and environmental testing industries for method development, validation, and accurate quantification of its non-deuterated counterpart.

Application

• Internal Standard for LC-MS/MS: Used as a deuterated internal standard in liquid chromatography-tandem mass spectrometry for the accurate quantification of m-tolunitrile and related metabolites in complex biological matrices.
• Pharmaceutical Research & Metabolism Studies: Enables precise pharmacokinetic and metabolic pathway analysis in drug discovery and development by tracking the fate of the parent molecule.
• Environmental Analysis: Facilitates the detection and measurement of trace levels of nitrile-based compounds or degradation products in environmental samples.
• Agrochemical Testing: Supports residue analysis and environmental fate studies of pesticides and herbicides that contain or degrade to similar nitrile structures.
• Forensic Toxicology: Assists in the definitive identification and quantification of specific analytes in forensic investigations.
• Chemical Synthesis Research: Acts as a labeled starting material or intermediate in the synthesis of more complex deuterated compounds for mechanistic studies.

Quality Control

Our m-Tolunitrile-D7 is manufactured under strict quality control protocols to ensure exceptional isotopic and chemical purity, essential for reliable analytical results. Each batch is characterized by NMR, HPLC, and Mass Spectrometry to confirm structural integrity, isotopic enrichment (typically >98 atom % D), and chemical purity. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory 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 nature, the container must be kept tightly sealed to minimize exposure to atmospheric moisture. For long-term storage, consider using desiccants or storing under an inert atmosphere.
