Description

o-Tolunitrile-D7 is a deuterated isotopologue of o-tolunitrile, where seven hydrogen atoms are replaced by deuterium. This high-purity labeled compound is essential for applications requiring precise analytical tracking and minimal background interference. It is primarily used by researchers and quality control laboratories in the pharmaceutical, agrochemical, and material science industries for use as an internal standard, tracer, or building block in synthesis.

Application

• Internal Standard for Mass Spectrometry (MS): Used for the accurate quantification of o-tolunitrile and related compounds in complex biological or environmental matrices.
• Metabolic Pathway Tracing: Serves as a stable, non-radioactive tracer in pharmacokinetic and drug metabolism studies.
• NMR Spectroscopy Solvent & Reagent: Acts as a deuterated solvent or reagent in nuclear magnetic resonance (NMR) analysis to prevent signal interference.
• Chemical Synthesis Intermediate: Employed as a deuterium-labeled building block in the synthesis of more complex labeled pharmaceuticals or specialty chemicals.
• Quality Control & Method Development: Critical for developing and validating sensitive analytical methods in regulatory and R&D environments.
• Material Science Research: Used in studies investigating reaction mechanisms or material properties where hydrogen/deuterium isotope effects are relevant.
