Description

4-Methylpentanoic-D11 Acid is a deuterium-labeled isotopologue of 4-methylpentanoic acid, where eleven hydrogen atoms are replaced by deuterium. This high isotopic purity is critical for applications requiring non-interfering internal standards and precise metabolic or environmental tracer studies. It is an essential analytical standard for researchers and quality control laboratories in the pharmaceutical, agrochemical, and environmental science sectors.

Application

• Internal Standard for Quantitative Analysis by GC-MS or LC-MS
• Tracer Compound in Metabolic Pathway and Pharmacokinetic Studies
• Deuterated Building Block for the Synthesis of Labeled Complex Molecules
• Reference Material for Method Development and Validation in Analytical Chemistry
• Use in Environmental Fate Studies and Degradation Pathway Analysis
• Component in the Manufacture of Deuterated Liquid Crystals or Polymers

Quality Control

Our 4-Methylpentanoic-D11 Acid is produced under strict quality systems to ensure exceptional isotopic and chemical purity. Each batch is characterized by advanced spectroscopic and chromatographic techniques, including NMR, GC-MS, and HPLC. A comprehensive Certificate of Analysis (COA) detailing isotopic enrichment (atom % D), chemical purity, and identity confirmation is provided with every shipment to support your regulatory and research requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). As a strong acid/organic solvent, keep away from incompatible materials such as strong bases and oxidizing agents.
