Description

Sodium 2-Methylpropionate-1-13C is a sodium salt of isobutyric acid specifically labeled with a carbon-13 atom at the 1-position. This stable isotope-labeled compound is a critical tool for advanced analytical research, enabling precise metabolic pathway tracing and quantitative analysis. It is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and life science industries who require high-purity, isotopically enriched building blocks for synthesis and diagnostics.

Application

• As a stable isotope-labeled internal standard for the accurate quantification of isobutyrate and related metabolites in complex biological matrices using GC-MS or LC-MS.
• For metabolic flux analysis and pathway elucidation studies in microbiology, plant science, and mammalian cell culture research.
• In the synthesis of carbon-13 labeled pharmaceutical intermediates and active pharmaceutical ingredients (APIs) for drug development and pharmacokinetic studies.
• As a precursor for manufacturing isotopically labeled agrochemicals and their metabolites for environmental fate and residue analysis.
• Use in NMR spectroscopy as a probe to study molecular structure, dynamics, and reaction mechanisms due to the distinct signal of the 13C label.
• For clinical diagnostics development, particularly in assays for inborn errors of metabolism involving branched-chain amino acid pathways.

Quality Control

Our Sodium 2-Methylpropionate-1-13C is manufactured under strict quality systems to ensure exceptional isotopic and chemical purity for research applications. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing isotopic enrichment (Atom % 13C), chemical purity, and identity confirmation. We adhere to stringent analytical protocols including NMR, MS, and HPLC to guarantee batch-to-batch consistency and reliability for your critical studies.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to prevent absorption of atmospheric moisture, which can affect stability and handling properties.
