Description

1,4-Dichlorobenzene-D4 CAS NO 3855-82-1 is a deuterated analog of 1,4-dichlorobenzene, where four hydrogen atoms are replaced by deuterium, serving as a stable isotope-labeled internal standard. This high-purity compound is critical for ensuring analytical accuracy and reliability in quantitative mass spectrometry and NMR spectroscopy. It is an essential tool for researchers and quality control laboratories in the pharmaceutical, environmental, and agrochemical industries who require precise measurement and traceability in their analytical methods.

Application

• Internal Standard for Mass Spectrometry (MS): Used as a quantitative reference standard in GC-MS and LC-MS analyses for accurate measurement of 1,4-dichlorobenzene and related compounds.
• NMR Spectroscopy Solvent & Reagent: Employed as a deuterated solvent or shift reagent in nuclear magnetic resonance studies due to its isotopic purity.
• Pharmaceutical Research & Metabolism Studies: Facilitates drug metabolism and pharmacokinetics (DMPK) research by tracking labeled compounds in biological systems.
• Environmental Analysis: Essential for the precise quantification of chlorinated benzene pollutants in air, water, and soil samples.
• Chemical Synthesis Intermediate: Acts as a labeled building block for synthesizing more complex deuterated organic molecules.
• Quality Control & Method Validation: Provides traceable standards for validating analytical methods and ensuring regulatory compliance in manufacturing.
