Description

n-Pentyl-D11-Benzene is a deuterated aromatic compound where all eleven hydrogen atoms on the pentyl chain are replaced by deuterium. This high isotopic purity makes it an essential internal standard and tracer in advanced analytical chemistry, particularly for mass spectrometry and nuclear magnetic resonance (NMR) studies. It is primarily used by researchers and quality control laboratories in the pharmaceutical, agrochemical, and environmental analysis sectors to ensure accurate quantification and metabolic pathway tracing.

Application

• Internal Standard for Mass Spectrometry (MS): Used in GC-MS and LC-MS analyses for the precise quantification of aromatic hydrocarbons and their derivatives, correcting for instrument variability and matrix effects.
• NMR Spectroscopy Solvent & Tracer: Serves as a valuable probe in deuterium NMR studies for investigating molecular structure, dynamics, and reaction mechanisms without signal interference from protons.
• Pharmaceutical Research & Metabolism Studies: Acts as a stable isotopic label to trace the absorption, distribution, metabolism, and excretion (ADME) of pentyl-substituted drug candidates in preclinical research.
• Environmental Analysis: Employed as a reference standard in the analysis of petroleum hydrocarbons, fuel additives, and environmental contaminants for high accuracy and regulatory compliance.
• Chemical Synthesis Intermediate: Utilized in the synthesis of more complex deuterated compounds for use in various spectroscopic and kinetic studies.
• Polymer Science Research: Used to study polymerization mechanisms and the properties of polymers where deuterated monomers provide contrast in scattering techniques.

Quality Control

Every batch of our n-Pentyl-D11-Benzene is produced and tested to meet exacting standards for isotopic and chemical purity. We employ advanced analytical techniques, including NMR and GC-MS, to verify deuterium enrichment and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing isotopic purity (typically ≥98 atom % D), chemical purity, and specific tests is provided with each shipment to ensure traceability and support your research integrity.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flame. For long-term storage under an inert atmosphere such as argon or nitrogen is recommended to maintain isotopic integrity.
