Description

Pentanoic-D9 Acid is a deuterium-labeled isotopologue of valeric acid, where nine hydrogen atoms are replaced by deuterium, offering exceptional isotopic purity for advanced analytical applications. This high-purity standard is critical for ensuring accuracy and reliability in quantitative mass spectrometry and nuclear magnetic resonance (NMR) spectroscopy. It is an essential tool for researchers and quality control laboratories in the pharmaceutical, agrochemical, and environmental science sectors, where precise internal standardization and metabolic pathway tracing are required.

Application

• Internal Standard for Mass Spectrometry (MS): Used as a quantitative reference standard in GC-MS and LC-MS analyses for accurate measurement of valeric acid and related compounds.
• Metabolic Research & Tracer Studies: Enables the detailed study of fatty acid metabolism, absorption, and biochemical pathways in pharmaceutical and nutritional research.
• NMR Spectroscopy Solvent & Reagent: Serves as a deuterated solvent or reagent in NMR experiments to eliminate interfering proton signals.
• Pharmaceutical Impurity Profiling & Method Development: Critical for developing and validating analytical methods to identify and quantify impurities and degradants.
• Environmental Analysis: Acts as a stable isotope-labeled standard for tracing volatile fatty acids in environmental samples and complex matrices.
• Chemical Synthesis Intermediate: Used in the synthesis of more complex deuterated compounds for research and development.

Quality Control

Every batch of Pentanoic-D9 Acid CAS 115871-50-6 is manufactured and analyzed under strict quality management systems to ensure the highest isotopic and chemical purity. Our products undergo rigorous quality testing, including NMR and mass spectrometry, to ensure compliance with exacting research standards. A comprehensive Certificate of Analysis (COA) detailing isotopic enrichment (typically ≥98 atom % D), chemical purity (by GC), and other critical parameters is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at controlled room temperature (15-25°C) in a cool, dry, and well-ventilated area. Keep away from strong bases, oxidizing agents, and sources of ignition. Due to its nature as a strong acid/organic solvent, handle with appropriate personal protective equipment in a fume hood.
