Synonyms: Pentadecanoic Acid, Pentadecylic Acid, C15:0 Fatty Acid, n-Pentadecanoic Acid, Pentadecanoic Acid (C15:0), Hexadecanoic Acid Impurity, Odd‑Chain Fatty Acid
Pentadecanoic Acid is a saturated straight‑chain fatty acid with 15 carbon atoms (C15:0). It is a naturally occurring odd‑chain fatty acid found in small quantities in dairy fat, certain fish oils, and some plant oils. Unlike even‑chain fatty acids (e.g., palmitic acid C16:0, stearic acid C18:0), pentadecanoic acid is relatively rare in nature and has attracted interest for its potential health benefits.
Pentadecanoic acid has been studied for its role as a biomarker of dairy fat intake and its potential association with reduced risk of cardiovascular disease, type 2 diabetes, and inflammation.
It is also used as an internal standard in fatty acid analysis and as a reference compound for lipid research.
Research application: Used as an internal standard for fatty acid analysis (GC).
Health biomarker: Indicator of dietary fat intake, particularly dairy fat.
Cardiovascular health: Associated with favorable lipid profiles in epidemiological studies.
Anti‑inflammatory support: May modulate inflammatory pathways.
Skin barrier support: Potential role in maintaining skin barrier function.
Source: Synthetic
Standardization: ≥98.0% pentadecanoic acid (GC)
Forms: White to off-white crystalline powder
Applications: Analytical standards, lipid research, nutritional studies
Q: What is the significance of pentadecanoic acid as a biomarker?
A: Pentadecanoic acid is a reliable biomarker for dairy fat intake, as it is present in significant amounts in milk, cheese, and butter. Its levels in blood are correlated with dairy consumption.
Q: Is pentadecanoic acid essential?
A: Pentadecanoic acid is not classified as an essential fatty acid, but it may have health benefits, including associations with reduced inflammation and improved lipid profiles.
Q: What purity grades are available?
A: We supply pentadecanoic acid with ≥98.0% purity (GC).
Q: How is pentadecanoic acid analyzed?
A: Pentadecanoic acid is typically analyzed by GC‑FID or GC‑MS, often as a fatty acid methyl ester (FAME) derivative.
Q: Is pentadecanoic acid stable at room temperature?
A: Yes, pentadecanoic acid is stable at room temperature when stored in a sealed container, protected from light and moisture. Long‑term storage is recommended at 2–8°C.
