Description

Pentanoic-5,5,5-D3 Acid is a deuterium-labeled isotopologue of valeric acid, where three hydrogen atoms at the terminal methyl group are replaced by deuterium. This stable isotope-labeled compound is essential for use as an internal standard in quantitative mass spectrometry, ensuring high analytical accuracy and reproducibility. It is primarily utilized by researchers and quality control laboratories in the pharmaceutical, agrochemical, and metabolomics fields for precise quantification and metabolic pathway tracing.

Application

• Internal Standard for GC-MS and LC-MS analysis in bioanalytical and environmental testing.
• Tracer compound in metabolic flux and pharmacokinetic (PK/ADME) studies within pharmaceutical R&D.
• Deuterated reference material for nuclear magnetic resonance (NMR) spectroscopy.
• Precursor for synthesizing more complex deuterium-labeled fine chemicals and active pharmaceutical ingredients (APIs).
• Use in stable isotope dilution assays for accurate quantification of short-chain fatty acids in complex matrices.
• Quality control and method development in analytical laboratories requiring high-purity isotopic standards.

Quality Control

Our deuterated compounds are produced under strict quality management systems to ensure high isotopic purity and chemical integrity. Each batch is characterized by NMR and MS to confirm isotopic enrichment and chemical purity. Certificates of Analysis (COA) detailing isotopic purity (atom % D), chemical purity (by GC or HPLC), and specific tests are provided to support your research and compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). 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.
