Description

Hexadecanoic-13,13-D2 Acid is a stable isotope-labeled analog of palmitic acid, specifically deuterated at the 13-position. This precise labeling makes it an essential internal standard and tracer for advanced analytical and metabolic research, ensuring accurate quantification and pathway elucidation. It is primarily required by researchers and manufacturers in the pharmaceutical, biotechnology, and analytical chemistry sectors for applications in mass spectrometry, NMR spectroscopy, and lipid metabolism studies.

Application

• Internal Standard for Mass Spectrometry (MS): Used for the precise quantification of palmitic acid and related lipids in complex biological matrices.
• Metabolic Tracer Studies: Enables the tracking of fatty acid metabolism, β-oxidation, and lipid synthesis pathways in vivo and in vitro.
• Nuclear Magnetic Resonance (NMR) Spectroscopy: Serves as a probe for studying molecular structure, dynamics, and interactions without signal interference from natural abundance protons.
• Pharmaceutical Research & Development: Critical for drug metabolism and pharmacokinetics (DMPK) studies of lipid-based therapeutics.
• Biochemical Research: Facilitates investigations into lipid signaling, membrane biophysics, and enzyme kinetics.
• Quality Control & Reference Material: Acts as a certified reference material (CRM) for calibrating analytical instruments and validating methods.

Quality Control

Our Hexadecanoic-13,13-D2 Acid is produced under strict quality management protocols to ensure high isotopic and chemical purity, critical for research integrity. Each batch is characterized by advanced analytical techniques including NMR, GC-MS, and HPLC to confirm isotopic enrichment and chemical identity. A comprehensive Certificate of Analysis (COA) detailing purity, isotopic abundance, and analytical results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C. This compound is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) when possible to prevent oxidation and moisture absorption. Keep the container in a cool, dry, and well-ventilated area.
