Description

4-Methylpentanoic Acid-D12 is a deuterated isotopologue of 4-methylpentanoic acid, where twelve hydrogen atoms are replaced with deuterium. This high isotopic purity is critical for applications requiring non-interfering internal standards and precise metabolic or environmental tracing. It is an essential analytical reagent for researchers and quality control laboratories in the pharmaceutical, agrochemical, and environmental science sectors. The compound's labeled structure provides unmatched specificity in mass spectrometry and NMR spectroscopy.

Application

• Internal Standard for Quantitative Analysis: Serves as a stable, non-interfering reference in GC-MS and LC-MS for quantifying the non-deuterated form or related metabolites.
• Metabolic Pathway Studies: Used as a tracer in pharmaceutical and biochemical research to elucidate drug metabolism and biological pathways.
• Environmental Fate Analysis: Employed in environmental science to study the degradation, absorption, and transport of organic acids and related compounds.
• Polymer & Material Science Research: Acts as a labeled monomer or additive precursor for investigating polymerization mechanisms and material properties.
• NMR Spectroscopy Solvent & Reagent: Provides a deuterated chemical shift reference or a building block for synthesizing other labeled compounds.
• Pharmaceutical Impurity Profiling: Utilized in method development and validation to identify and quantify process-related impurities.

Quality Control

Every batch of 4-Methylpentanoic Acid-D12 is manufactured and tested under strict quality management systems. We guarantee high chemical and isotopic purity, with comprehensive testing including assay, isotopic enrichment (D%), and identification. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting all critical parameters to ensure compliance with your research and analytical standards.

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, oxidizers, and sources of ignition. Due to its nature as a strong acid/organic solvent, handle with appropriate personal protective equipment in a fume hood or well-ventilated area.
