Description

Hexadecanoic-15,15,16,16,16-D5 Acid is a stable isotope-labeled analog of palmitic acid, where five hydrogen atoms are replaced by deuterium at specific positions. This high-purity labeled compound is essential for applications requiring precise internal standards and metabolic pathway tracing. It is primarily used by researchers and manufacturers in the pharmaceutical, analytical chemistry, and life science sectors for advanced quantitative analysis.

Application

• Internal Standard for Mass Spectrometry (MS): Provides accurate quantification of palmitic acid and related metabolites in complex biological matrices like plasma, serum, and tissue samples.
• Metabolic Pathway Tracing: Enables detailed studies of lipid metabolism, β-oxidation, and fatty acid synthesis in pharmacological and nutritional research.
• Pharmaceutical R&D: Used in the development and validation of bioanalytical methods for drug metabolism and pharmacokinetics (DMPK) studies.
• Clinical Diagnostics: Serves as a critical component in assays for diagnosing and monitoring metabolic disorders such as diabetes and cardiovascular diseases.
• Nutritional Science Research: Facilitates the investigation of dietary fat absorption, distribution, and utilization in vivo.
• Environmental & Food Analysis: Acts as a stable isotope-labeled standard for the precise detection and measurement of fatty acids in environmental and food safety testing.
